C64 Emulator Bugs

after stumbling about a bunch of VICE bugs myself in the last couple of days i have decided to compile a list with issues current emulators have. the goals for this are

- make people aware that emulators are by far not perfect (yet?)
- make it easier for emulator authors to improve the emulators, by showing problematic programs and possibly provide simple testcases
- allow c64 coders to implement emulator detection if desired

so well, check this: http://hitmen.c02.at/files/docs/c64/c64_emulator_bugs.txt

help welcomed :)

TRC+TBI Intro 10 doesn't seem to work on any emulator.

and uh yes, red storm definetly doesn't crash on the real thing (no idea about the flickering).

Groepaz closed his account?
And didn't Red Storm use to work in earlier versions of Vice? I mean, how else did I get the screenshots? ;-)

The red storm image from the first link crashes all emulators, I haven't tested real C64 but I will.
The red storm image from c64.ch runs fine on VICE. So probably the image from the first link is broken.

And just for the records: The removed images crashes on my real thing. And the flickering raster is also visible (even at the lower one if your TV displays enough of the left border).

TRC/TBI intro bug is confirmed. Probably related to a "IRQ cannot be aknowledged just before it starts" bug in VICE that is known for a long time but hard to fix.

Hello.

- [vice,hoxs] Tsunami/Booze Designs Tsunami

"The interlaced girl in the demo Tsunami features 8 bad pixels on her nose when running on
VICE (as HCL stated in the note IIRC)"

"Well spotted, the glitch is visible in Hoxs64 too. CCS64 v3.3 isn't affected by this."

"abo: Problem is identified, patch needs further investigation"


Hoxs64 no longer affected, works in v1.0.4.26+.

Bad file, at end there are $fe bytes (one entire sector) all zeroed, and seems too short because decrunch routine reads from $7ddd, there is nothing there. Most probably there was a bad sector in the middle of the file.
