I'd suggest submitting the RBF to Krikzz, by the way. Whenever he does another Everdrive OS update I'm sure he'd want to include it.
Yeah, I've actually been in touch with Krikzz since early January about this mapper30 implementation, as I can't really figure out why it won't even run on the AVS. I don't have an AVS myself and no plans to get one either, but I'd like this implementation to work for AVS owners too.
The original 002.RBF from the mapper example I used had the same problem of not working at all, so it appears that the mainline release has had accidental fixes done to it after that example was released, that somehow made it work on AVS, and which not even Krikzz himself can recall anymore, as he hasn't even observed that issue on the AVS himself.
Unfortunately he's also been too busy to provide a newer cleaned-up mapper example source from the current mainline. And I can't really try much out myself when I can only toss wild ideas into the build, and ask an AVS user in a different time zone to re-test it only to see a gray screen again...
But hmm, just realised now though that the MMC5 example released later has a slightly newer timestamp, and also has some extra code related to the reset signal. So maybe this could be the missing link... I'll try to look into this in the weekend.
