Aside from Tengen Camerica (aladdin enhanced or not) made some quality stuff in some of their releases. Beyond that I won't touch the stuff outside roms as the Color Dreams/WT, AVE, HES, etc stuff is at best mediocre being generous and mostly awful where they should pay you for the pain and suffering involved.

I grabbed a Micro Machine game over the weekend and it's surprisingly fun. I wanted it to see how things were shaking out on the R5 having heard Camerica games had problems or just didn't work. I'm thinking I may scramble for a copy of Linus Spacehead as I heard it's ok too. I know where to find an aladdin version of it within the adapter for like $20, probably a good deal but I wouldn't know as I don't price those things. :P
