Looking for anyone deep in Sega System 16 Z80 sound driver internals.

I've ripped the YM2151 voice patches from the sound ROM ($0E4E table on Shinobi). What I'm missing is the SFX
choreo voice note duration for in-game effects like the shuriken.

Anyone help?

This weeks work on Shinobi for the CommanderX16!

The music is awesome on the CX16, using the same sound chip helps a lot. A few details like jumping over the barriers correctly took a lot of time.

Next up: saving VRAM.

Today is going to be spent authoring collision on the original Shinobi maps using the excellent Tiled from @bjorn .

I might have a pop and completing some of the weird maps left in the ROM too.

Dev Update 2 on my Shinobi: Commander X16 rewrite.

I've moved to arcade fidelity graphics, which look absolutely awsome on the Commander X16!

I've been experimenting with C using llvm-mos for the Commander X16 over the last week, and have managed to get a pretty good sprite system up and running using Shinobi sprites ripped from the arcade ROM.

Joe is made up of two sets of sprites, top and bottom.

I don't know if this will turn into something yet, but it's pretty cool to see an 8-bit system do stuff like this.
