Work in progress SDK for creating Game Boy Advance games using Zig programming language.

ziggba's Issues

Issue when compiling on macOS

/Users/pomettini/Git/ZigGBAHelloWorld/build.zig:8:25: error: container 'std' has no member called 'Target' exe.setTheTarget(std.Target {

Any idea of why this happens? I apologize for the newbie question, but I'm moving my first steps with Zig :)

Key input demo

Finish other tiles demo

Do 8-bit (Mode 4) of Bitmap,

Build of examples with added c file fails.

Build of examples with added c file fails. There is a warning

warning(link): unexpected LLD stderr:
ld.lld: warning: Linking two modules of different target triples: C:\Users***\Desktop\ZigGBA-master\zig-cache\o\2e71dea1b90155b4f26cf1ea3866b2fd\keydemo.o' is 'thumb-unknown-unknown-eabi' whereas 'ld-temp.o' is 'armv4t-unknown-unknown-eabi'

for every failed demo

VS Code project files committed

Was this intentional?

Add “zig” and other relevant topics to repo

Use different bitmap for keydemo when we support import of palette-indexed image format

Replace usage of C source from TONC by a different image done in a palette-indexed image format

`mode4flip.gba` fails to build

I'm a bit new to zig so apologies for what might appear as a poor bug report.

I've installed the latest master from the website and I'm getting a compiler error when trying to build ZigGBA. I did a clean install, cache, and followed the instructions.

I see another bug report from 2021 looks like a very similar issue. I will post here if I find a solution. Something appears to be building for the wrong architecture and then attempting to link to it.

Also, the README references a version of Zig master that doesn't seem to exist yet ("0.11.0-dev.6533+d3c9bfada"). Can you explain where this can be found?

Expose save ram to the API

Memory map: 0E000000-0E00FFFF Game Pak SRAM (max 64 KBytes) - 8bit Bus width

• Maybe simple SaveRam.save(saveRamType: comptime type, saveRam: saveRamType)

Replace usage of @bitCast

Replace usage of @bitcast with safer alternatives, it needs to work in debug builds

Add a fourth pixel

It could be white or yellow
