I don't have an A600GS but have definitely completed the game via that route on hardware and UAE. Will have a look into it for the next release to see if I can figure out what might be causing the issue.
Just confirmed my HD image does work when running under UAE, and I also tried it on my Turbo Chameleon Minimig core (slow as it is on that), which did exactly the same as my A600GS, with the game crashing at the end of the final stage with an 8000 000A error code.
I hope it the A600GS crash problem can be fixed, as the game really does run superb on it otherwise.
Sorry for replying so many times, but I made a new HD image, ripping the ROMs myself (the first one I cheated by using files from JOTD's WHDload image), and tested again on my A600GS.
Ending D still crashes, this time it just exited back out to the A600GS menu.
Ending B & C both WORK, going through to the ending as normal.
I am still working on getting to endings A&E, I've found playing what is effectively the arcade version with digital controls (as opposed to steering wheel or even analog stick) is downright hard.
I'll keep you posted if I get ending A&E.
Oh, and I played to ending D 3 times on UAE, and one of those times it crashed there too.
OK last post about it for now, I reached ending A & E and they both worked too.
So all endings worked except for that pesky ending D, crashing the game at the end of the final stage as soon as the game takes over control of the car. On A600GS and one time using UAE too.
Thanks again for an awesome conversion.
Now patiently waiting for the next release...
