Thank you! Took a bit of trial and error, but the AS version is now identical to the ASM68K one.
A small but potentially useful tool born out of my explorations of Sonic CD Mode 1 and taking some inspiration from MarkeyJester's TwizzlerDec: a...
The DMA delay issue affects 1M mode as well? I had been under the impression that it didn't, given that Sonic CD's FMV handlers DMA directly from...

From this sentence alone, I'm getting the impression that the velocities you're calculating (or something related to them) are being mistreated as...
While probably not the most important, optional emulation of the TMSS would be a nice little touch. Could probably even write a custom bootrom for...
Thankfully I have a copy of retail Sonic CD in bin+cue format, and that worked. And after adding support for the stub BIOS to my Mode 1 init code,...
Trying this for the first time, and I've run into a slight snag: I tested a couple Genesis ROMs just fine, but I can't get Mode 2 CD software to...
Might as well throw my own hardware in the running. I have a full North American Sega CD setup, Model 1 VA2 paired with a Funai Model 2. Former...
Went ahead and made an ASM68K version (mostly just a matter of modifying the macros). And FWIW, threw in an optimization to EniDec_End.got_byte....
I actually liked the older version since it's a bit more precise with identifying the sub CPU device (storing the ID of the BIOS entry in RAM...
A small milestone from my effort to make a Mode 1 version of Sonic CD, even if it's a feature that won't be used in the long run. This test ROM...
