JaDogg / blw4

WASM4 native runtime ported to 32blit (32blit SDK)

32-Blit WASM4

What is this?

• WASM4 fantasy console emulator for 32Blit.
• Repo created using 32blit boilerplate

Controls

WASM4 Control	32Blit Control
X	X
Z	Y
Up	Up
Down	Down
Left	Left
Right	Right
Mouse Left	A
Mouse Right	B
Mouse Middle	Joystick Button
Mouse Move	Joystick
Select Game	Reset

Possible Problems:

• Possibly != 60FPS (Do not think this is possible to fix)
• Possibly != 64KB RAM for WASM4 (Need to check in 32blit)
• No net-play (Not sure about this)
• Sound working but not at 60FPS :(
  • Problem: should this be implemented as 40FPS or 60FPS?
• No disk save/load support. (Can attempt to implement this)
• Not part of original wasm4 github repo (At the moment I did not expect this to work at all, so I didn't fork it)
  • Various changes cross files were done.

Usage

• Copy the blw4.blit then *.wasm file to sd card.
• You can find more carts at https://wasm4.org/play

Notes

Setting up SDKs

Installing cross-compiler and C library, sdl2

sudo pacman -S arm-none-eabi-gcc arm-none-eabi-newlib arm-none-eabi-binutils sdl2 sdl2_image sdl2_net
python3 -m pip install 32blit

Cloning SDKs

# I couldn't get the auto download work. So I cloned it to parent directory of this folder
git clone --recurse-submodules -j8 [e-mail]:raspberrypi/pico-sdk.git
git clone --recurse-submodules -j8 [e-mail]:pimoroni/picosystem.git
git clone --recurse-submodules -j8 [e-mail]:32blit/32blit-sdk
git clone --recurse-submodules -j8 [e-mail]:raspberrypi/pico-extras

Cloning original WASM4 (You do not need this)

git clone --recurse-submodules -j8 [e-mail]:aduros/wasm4.git
