old bug, just forgot to track it.

See 240p test suite ROM.

Some register isn't quite getting cleared out on reset?

Causes nothing but headaches.

Presumably due to inaccurate sprite cache emulation. Should probably rewrite it some time.

Uses raster effects on sprite Y positions, requires accurate sprite cache behavior.

Gets stuck on SEGA logo or black screen, seemingly randomly.

Used to work, but before repo was created. Not sure if HyperRAM specific.

EA logo glitches on every game that has it. Not critical though, as the games work beyond that.

Attempting to soft-reset this game (outside of title screen) often leads to violent glitches, sometimes even crashing the P2 entirely.

Quit-to-menu seems to be a non-issue though.

When there's many monsters on the screen, some section of them disappear.

Another "sprite table raster effect" type issue, I think. Need to do that sprite cache rewrite.

Xeno Crisis and 240p test suite in particular. IIRC the SGDK examples also exhibit this.

Known issue, just forgot to add to tracker until now.

Shadows always render at the smallest size.

TODO: Framegrab of issue

• Sonic 1 is borked
• Worm boss in Mega Turrican is invisble
• possibly more

These worked at some point, seem broken now. Not sure if HyperRAM specific.

Music slows down, even though game is running at full speed.
Very noticable in the 1st stage boss fight.

Presumably also happens in the actual level.
