Amiga 1000 and USB HxC having issues with ADFs

[SinCity]

Obtained the Kickstart ADF and loaded that first. Then load an ADF. I'm getting a lot of Guru Mediation errors and have not been able to load any image other than Kickstart. Some games just freeze when loading. Some games do not display properly (maybe PAL instead of NTSC). Some games have a lot of pixilation. I have Arkanoid on a real floppy and it works. Does not work well using HxC, there are a lot of artifacts in the display.

The ST has been successful and Amiga a failure.

Increase the buffer size in the setting window.

I played around with Shuffle Puck Café. I was able to load it by changing packet size to 3549 with minor screen artifacts uding game screen. Other screens are fine. Sky Fox loaded, but lots of artifacts on the screen. Other images didn't load successfully. Bad images?

EDIT: My USB Emulator is Rev D from Lotharek.

Set it to 2560 and retry.
If possible increase the hxc process priority.

[SinCity]

No difference with Packet set to 2560 and priority HIGH. Same issues.

quite strange... Can you try to start the WB from the HxC?

[SinCity]

Finally have time to try it again. Workbench 1.1 works fine. Tried the following images:

Alien Syndrome-Loads and plays and then graphics distort.


Formula 1 Grand Prix-Loads and plays but car has extra pixels.


Grand Slam Tennis-Loads and plays but character graphic has extra pixels like the car above.
City Defense-Plays with no issues.
Prince of Persia-Loads welcome screen and locks up.

Very strange. this look like to be a DRAM issue.
Can you retry with another Amiga?

[SinCity]

I only have the one Amiga. When I have more time, I'll try the same games that I have on floppies.
