Overview

Mooneye GB

Mooneye GB is a Game Boy research project and emulator written in Rust.

The main goals of this project are accuracy and documentation. Some existing emulators are very accurate (Gambatte, BGB >= 1.5) but are not documented very clearly, so they are not that good references for emulator developers. I want this project to document as clearly as possible why certain behaviour is emulated in a certain way. This also means writing a lot of test ROMs to figure out corner cases and precise behaviour on real hardware.

For documentation about known behaviour, see Game Boy: Complete Technical Reference

Binary test ROMs are available here in a zip package and also as individual .gb files. They are automatically built and deployed whenever there's new changes in the master branch.

Non-goals:

CGB (Game Boy Color) support. It would be nice, but I want to make the normal Game Boy support extremely robust first.
A debugger
A good user interface. Building native UIs with Rust is a bit painful at the moment.

Warning:

Project is WIP
Doesn't work properly without a boot ROM
The emulator is lagging behind hardware research. I don't want to spend time making short-lived and probably incorrect fixes to the emulator if I'm not sure about the hardware behaviour.

Hardware testing

There's tons of documentation and tons of emulators in the internet, but in the end I only trust real hardware. I follow a fairly "scientific" process when developing emulation for a feature:

Think of different ways how it might behave on real hardware
Make a hypothesis based on the most probable behaviour
Write a test ROM for such behaviour
Run the test ROM on real hardware. If the test ROM made an invalid hypothesis, go back to 1.
Replicate the behaviour in the emulator

All test ROMs are manually run with these devices:

Additional devices

I also have access to more devices with different mainboard revisions, but I think the CPU revision is all that matters if we study the behaviour and not analog characteristics (e.g. audio filtering). Even if audio sounded different between two units with the same CPU revision but different mainboard revisions, I'd expect the difference to be caused by individual device variation or different revisions of support chips (e.g. RAM/AMP/REG).

The main "test fleet" is already very big, so I will only use these devices if there's evidence of behaviour that depends on mainboard revision or individual units.

I'm still looking for the following mainboards, but these are probably not required for reverse engineering:

SGB-R-01
SGB-N-01
SGB-N-10
C/AGS-CPU-20
DOL-GBS-01

For now, the focus is on DMG/MGB/SGB/SGB2 emulation, so not all tests pass on CGB/AGB/AGS or emulators emulating those devices.

Performance

Always compile in release mode if you care about performance!

On a i7-3770K desktop machine I can usually run ROMs with 2000 - 4000% speed. Without optimizations the speed drops to 150 - 200%, which is still fine for development purposes.

Raspberry Pi with X11 desktop works but is too slow because there is no OpenGL acceleration.

The emulator is runnable on Android, but cross-compiling and packaging is a huge pain and touch controls would have to be implemented, so I'm not supporting Android at the moment.

Running the emulator

Requirements:

Rust 1.26
SDL2 development libraries for your platform must be installed

GUI

cargo run --release
Follow the instructions

Command-line

Acquire a Game Boy bootrom, and put it to $HOME/.local/share/mooneye-gb/bootroms/dmg_boot.bin
cargo build --release
cargo run --release -- PATH_TO_GAMEBOY_ROM

On Windows, also download an SDL2 package containing SDL2.dll, and put it to target/debug and target/release.

Notes:

cpu_instrs fails on MGB/SGB2 hardware and emulators emulating them correctly. The ROM incorrectly detects the device as CGB, and attempts to perform a CPU speed change which causes a freeze (STOP instruction with joypad disabled)
dmg_sound-2 test #10 can fail randomly on real hardware and seems to depend on non-deterministic behaviour.
oam_bug-2 fails on all CGB, AGB, and AGS devices
cgb_sound-2 test #03 fails on CPU CGB, CPU CGB A, and CPU CGB B

Test naming

Some tests are expected to pass only a single model:

dmg = Game Boy
mgb = Game Boy Pocket
sgb = Super Game Boy
sgb2 = Super Game Boy 2
cgb = Game Boy Color
agb = Game Boy Advance
ags = Game Boy Advance SP

In addition to model differences, CPU revisions can affect the behaviour. Revision 0 refers always to the initial version of a CPU (e.g. CPU CGB). AGB and AGS use the same CPU models. The following CPU models have several revisions:

DMG: 0, A, B, C
CGB: 0, A, B, C, D, E
AGB: 0, A, A E, B, B E. Revision E also exists, but only in Game Boy Micro (OXY) so it is out of this project's scope. However, A E and B E are most likely actually just E revision in A or B-compatible package.

In general, hardware can be divided to a couple of groups based on their behaviour. Some tests are expected to pass on a single or multiple groups:

G = dmg+mgb
S = sgb+sgb2
C = cgb+agb+ags
A = agb+ags

For example, a test with GS in the name is expected to pass on dmg+mgb + sgb+sgb2.

Build Error

I tried to build this emulator, but I get the following build error (on MacOS):

  --> src/frontend/renderer.rs:57:7

   |       ^^^^^^^^^^^^^^^^ help: consider using a reference: `&FrameState::Even`

Any ideas what is causing this and how to fix? Thanks! Very interested in and excited about this project.

Added several timer tests.

I extracted a couple of tests from my old gb tests rom and also created a few more additional timer tests.

I was only able to test them on MGB, CGB, and AGS units.

In ie_push.s, cannot trigger "R3: unwanted cancel" failure ?
When I tried this test with my emulator, instead of failing or passing, the emulator just stopped after a while. As I was investigating why, it occurred to me that my implementation should have triggered the "R3: unwanted cancel" failure but that it didn't for some reason.

My understanding of the scenario that should lead to this failure is as follows:

from address PC=0x0235 with SP=0x0001, we trigger INTR_SERIAL with "ldh (<IF), a"

while processing this interrupt, if it is cancelled, PC is set to 0

because at the end of ie_push.s we have ".org $0000" followed by "jp hl", when executing the instruction at PC=0, we should jump to the address contained in HL

However, because we trigger the interrupt with SP=1, pushing PC as part of processing the interrupt not only puts 0x35 into IE but it also puts 0x02 at the address 0 which replaces the 0xE9 opcode of the jump instruction that should trigger the failure path.

Is my interpretation correct or did I miss something ?

Issue with sources-GS test

Hello,

I'm facing a problem with this test and I need your insight! At test_fe00: , it appears that OAM is cleared with call clear_oam , then DMA runs and the test compares the result with ram_pattern_1. Since OAM was cleared prior to DMA, it will never have the correct pattern, so you even have to remove the clear or reload the pattern before triggering the DMA.

I hope I didn't get the whole thing wrong! Keep up the great work!

Request for details on a test comment ( about OAM DMA )
I'm having trouble understand something I read in one of your timing tests that deals with OAM DMA.

https://github.com/Gekkio/mooneye-gb/blob/master/tests/acceptance/call_cc_timing.s#L83-L86

; the first two bytes of CALL nn will be at $FDFE, so ; the high byte of nn is at the first byte of OAM during testing ; [...] ; the memory read of nn is aligned to happen exactly one cycle ; before the OAM DMA end, so high byte of nn = $FF ; therefore the call becomes: ; call c, $ffca

From what I understand the CPU is only able to access HIRAM during OAM DMA.. so wouldn't that turn into RST $38 ($FF) instead?

Another piece of that test that is confusing to me is the per-cycle timings of CALL.

; CALL cc, nn is expected to have the following timing: ; M = 0: instruction decoding ; M = 1: nn read: memory access for low byte ; M = 2: nn read: memory access for high byte ; M = 3: internal delay ; M = 4: PC push: memory access for high byte ; M = 5: PC push: memory access for low byte

You state above that the low byte is read first. That seems to go against what the test expects if its expecting the low byte to be read correctly and the high byte to be read as $FF.

Wrong HalfCarry check on add16-instruction
Hey, I'm working on an GB emulator in F#.

While studying (or peeking ;)) your implementation I noticed a bug in this line: https://github.com/Gekkio/mooneye-gb/blob/master/src/cpu/mod.rs#L902

According to the most known Game Boy CPU Manual, as well as the official GB programming manual the half-carry flag is set when there's a carry from bit 11. This would mean a check for 0x0FFF, and not 0x07FF (bit 10).

A test case from the official developer manual (page 97):

When HL = 0x8A23 ADD HL, HL ; HL <- 0x1446, H <- 1, N <- 0, CY <- 1

Remove "debug" opcode from all test roms.

Please, remove it. The real behaviour of that pseudo-opcode (which, acording to wla-dx, is 0xED) is to hang the CPU forever. Most emulators show error messages when they try to execute that instruction. You should use "ld b,b", which is kind of a standard (no$gmb, bgb) and it doesn't hang emulators or real hardware. In fact, the only reason the test roms can work in real hardware is that just after that instruction there's an infinite loop, so the CPU would be trapped there anyway.

Bump simplelog from 0.9.0 to 0.12.0

Bumps simplelog from 0.9.0 to 0.12.0.

Changelog

Sourced from simplelog's changelog.

v0.12.0

- Replaces the semingly unmainted chrono library with the time crate.
- Addresses through this update 
    - RUSTSEC-2020-0159 (chrono)
    - RUSTSEC-2020-0071 (time)
- `ConfigBuilder::set_time_to_local` is replaced by `ConfigBuilder::set_time_offset_to_local`.
    - This function requires the new (and by default activated) `local-offset` feature.
    - This function may fail, for more information read the docs.
    - simplelog will not determine the local offset dynamically anymore, but only once, when this config option is set.
        - Due to safety reasons there is no way to provide this property currently.
- `ConfigBuilder::set_time_offset` now takes a `time::UtcOffset` instead of a `chrono::FixedOffset`.
- `ConfigBuilder::set_time_format` has been replaced by three new variants
    - `ConfigBuilder::set_time_format_rfc2822` sets the time format to use the format described by rfc2822.
    - `ConfigBuilder::set_time_format_rfc3339` sets the time format to use the format described by rfc3339.
    - `ConfigBuilder::set_time_format_custom` sets the time format to a custom time format best created using `time::macros::format_description`.
        - Runtime provided time format configuration is possible, but difficult due to lifetime constraints.
        - Fixing this will require a solution to https://github.com/time-rs/time/issues/429
    - *Note*: The default format is unchanged "[hour]:[minute]:[second]"

v0.11.0

- Add colored log levels using `ansi_term` (PR [#88](https://github.com/drakulix/simplelog.rs/issues/88), credits to @manio)
- Add target padding (PR [#85](https://github.com/drakulix/simplelog.rs/issues/85), credits to @bytebeamio)
- Add optional color and style support using `paris` crate (PR [#84](https://github.com/drakulix/simplelog.rs/issues/84), credits to @manio)

v0.10.2

- Fix flushing with `BufferedStandardStreams` (PR [#82](https://github.com/drakulix/simplelog.rs/issues/82), credits to @mrkline)

v0.10.1

- Fix TermLogger performance using `termcolor::BufferedStandardStream` (PR [#80](https://github.com/drakulix/simplelog.rs/issues/80), credits to @mrkline)
- Add write thread name support for `termlog` (PR [#76](https://github.com/drakulix/simplelog.rs/issues/76), credits to @zeroflaw)

v0.10.0

- Fix wrong argument naming (PR [#70](https://github.com/drakulix/simplelog.rs/issues/70), credits to @scvalex)
- *Breaking*: More color customization options (PR [#72](https://github.com/drakulix/simplelog.rs/issues/72), credits to @mrkline)
- Clarify docs on config levels
