Getting back into snesdev with a new side project, an spc700 assembler.
This assembler will make compiling Terrific Audio Driver a lot easier.

I'm off to a good start, it can currently assemble a single instruction inside unit tests.

New blog post:
A wordy overview and retrospective on the homebrew SNES game engine I used for my 2025 SNESDEV game jam submission.

I've been working on the Super Game Boy features for the Petal Crash Game Boy Color port, where you'll get a versus mode with two players on the same screen via having the Game Boy game take over the SNES side with its own code. I added all of the cursor animations over the past few days, and it's really cool seeing all of this polish!

This video is from me testing it standalone, but I did actually do a proof of concept uploading the code and running it on Super Game Boy. Just need to add code to upload the graphics too.

Announcing v0.2.0 of my homebrew SNES audio driver.

This release stabilises the 2 breaking changes I made to the audio driver months ago (in the beta releases). It also fixes a lot of small bugs and items I had on my ever growing todo list.

#snesdev #spc700

I have released a second public beta of my SNES homebrew audio driver.
This beta add transpose analysis to the MML compiler to detect all out-of-range notes caused by driver transpose.

I've also rewritten the timer code to increase the maximum bytecode sleep duration to 65535 ticks.

I aim to release v0.2.0 before the end of the year. I have 80 small things and bugs left to do on my checklist.

#snesdev #spc700

I have released a new public beta of my SNES homebrew audio driver. https://github.com/undisbeliever/terrific-audio-driver/releases/tag/v0.2.0-beta.1

This beta moves `_` and `__` transpose MML commands out of the MML compiler and into the audio driver, so the semitone offset will affect loops and subroutines.

#snesdev #spc700

I've added a transpose setting to my SNES audio driver.
Subroutines and loops can now be played with different semitone offsets.
Bytecode assembly only, the MML compiler changes have not been coded yet.
