Progress update.
SCSP:-fix Monitor register, now there is less stuttering when playing FMV.-added support for 8-bit PCM samples.VDP1: VRAM write speed during DMA is now close to the original.SCU: improved DMA operation.Now there are more playable games.
Progress update.
Several fixes to VDP1/2 and SCU. Now there are more runnable games. The VDP2 does not yet support all graphics modes for Rotation Scroll Screen, so there are some missing graphics in the background.The next task is to achieve the original DMA speed for B-Bus (VDP1 and VDP2).
Progress update.
Reworked the SCU DMA. Made a few changes to VDP1/VDP2, but there are still a lot of glitches, such as in Daytona USA (https://youtu.be/rWU0bri9CW4).
Fixes in CD module.
Fixed a bug in SH1 DMAC and now large data blocks from the CD drive are loaded correctly.
Still working on the CD module.
Now TOC and the boot sector are read correctly, but there is a failure when reading the Security Ring Data.
Working on a CD module.
Now SH1 reads TOC and sector data, but the main CPU receives damaged TOC .I keep working…
