whdload MMU setup will detect all wrong accesses to unknown memory, it can snoop registers for missing blitwaits, ...

less interesting when you have WinUAE but the "wrong access" part is more flexible in whdload.

Personally I'll be using it also to develop my own games now. And maybe after the game runs properly I'll switch to some less compatible but okay OS loader just to avoid the memory overhead (whdload needs to save chipmem and flashes when files aren't preloaded because of OS swaps)

About "new games" that could be fixed by their authors, yeah, that's true. But sometimes the original authors don't want for instance to add a second button for jump, trainer, ... and whdload provides that.

Also some games need "no startup" to run because of maxed out chipmem. Whdload doesn't need that. And I'm not talking about creating a routine that starts/stop the OS and doesn't leak memory, and handles MMU translation tables, caches... of all processors 68000/010/020/030/040/060...
