I've probably got those games in my Speccy emulator drawer and will have to give them a go to jog my memory of them.
@ all
Many thanks. I'm using an A4000 running WarpOS with Phase 5 Cyberstorm PPC 604e 233Mhz with 060/50 and Cybervision64/3D. The Cyberstorm PPC is actually in what I call my test rig A4000 with Workbench 3.1, 3.0 ROMS and Buster 9 :oops:
I've got Amigenerator from here:
http://www.amidog.com/amiga/amigenerator/And some ROM files for Sonic1, Sonic2 and WhipRush.
The file names are very long with spaces as you can see below. You have to start it with a command line so I made copies and renamed them as Sonic1.zip, Sonic2.zip and WhipRush.zip to get rid of the spaces. Hopefully this won't be a problem?

Typing 'Amigenerator.exe Sonic1.zip' triggers NEWMODE. After choosing 640x480 16bit the screen changes and it looks as though the program has started ok. But after about 1.5 seconds it goes back to shell with the report "Something has gone seriously wrong @ 006600E7"
Typing 'Amigenerator.exe Sonic2.zip' gives a black screen momentarily followed by the report "Invalid instruction @ 0000010C".
Typing 'Amigenerator.exe WhipRush.zip' gives a black screen momentarily followed by the report "Invalid instruction @ 00000168".
Here are some Scout screengrabs of my system......


Hmmmm... It appears that I am using Picasso96 drivers instead of the required Cybergraphx. Prehaps this is part of the problem?
I'm pretty new to the PPC but I can tell you that the WarpOS version of FroggerNG is working perfectly for video and movie playback. ShowPPC for picture display and AmigaAMP PPC version are also working fine.
