I'm not saying that there aren't any, just that from my experience more than 50% of what I tried works. I tried to run about 30 whdload games on the A500/A500+ (the only ones that interested me that don't have an hd install) and found that:
*50% runs, give or take. (1mb chip + 2mb fast)
*60% runs, give or take. (1mb chip + 4mb fast)
*60% runs, give or take. (2mb chip + 2mb fast)
*70% runs, give or take. (2mb chip + 4mb fast)
*80% runs, give or take. (2mb chip + 8mb fast)
Those that don't work with the best configuration are either due to:
a. The slaves requiring whdload 16+ which for some strange reason refuses to work at all with my A500/A500+ (garbled screen + guru, even with games that run on whdload 15)
b. Illegal access errors such as the one you describe in your other post.
Then again, YMMV. It all depends on which games you try, and which version of whdload works for you.
