@ -21,18 +21,11 @@ Still some lesser issues with cancelling a fadeout. Otherwise CDDA is working no
Arcade Card games:
- JANSHIN DENSETSU sets the T flag prior to an LDA instruction; MANY TIMES (ie it doesnt seem to be an accident).
Unclear if T flag actually affects LDA instruction.
- Madou Monogatari - Dies requesting more tracks than exist
- Ryuuko no Ken is all messed up, and I don't super care :|
- Tengai Makyo eventually died requesting 0 sectors read
- Rayxanber 2 weird issues at the end of first level with cd audio player
- Record of Lodoss War wont start game from title screen
- Snatcher dies at startup while polling subcode, demonstrating the incorrectness of subcode polling code.. yeah that hangs together
- Valis: Screen is black during entire intro section
- Valis III: Dies with 'request more tracks than exist'
card angels does poll subcode...
- Valis III: playable,gfx issue on title screen... possible due to not updating VDC regs on LSB? really should just fix that once at for all...
======= TurboGrafx compatibility issues =======
@ -42,6 +35,11 @@ General:
Most emulators simply crop the screen at a certain vertical range. For now, I have chosen not to do this.
Right now the emulator is simply displaying a framebuffer. Eventually, we will do an update that emulates NTSC.
But for now we're letting this be. There's no intermediate step between emulating a framebuffer and emulating a TV.
+ Adding to this, there are only a handful of Hucards that do crazy thing with screen resolution, and our framebuffer
approach mostly seems reasonable. On TurboCD the situation changes somewhat, while the normal "gameplay" screens
are pretty standard, the various intro screens tend to do much more crazy stuff with the 'active display region'
much more frequently than was done on Hucards, and our framebuffer/active display strategy starts to look more silly.
Oh well, though. Changing this is a Native Version Core feature, not a C# Core feature.
Eagan's Rendered Sprite Demo - demonstrates sprites that shouldnt be displayed (so does Turbo Engine!)
