hehe! I also have a Mitsumi CR-4804TE ....
I though nobody else had it...
Mine is 4x (only...) but never had problems burning saturn games... You just have to make sure you convert your isos from mode1/2048, to mode1/2352 (this burner only allows raw images)... but if you have to patch the country code, patch it when it is in mode1/2048, and then convert to mode1/2352, with iso2raw (you can find it on
here, download the dos package named dao.zip, iso2raw it's in there...
I always use fireburner/cdrwin ...
Maybe you don't have to do that mode1/2048 -> mode1/2352 conversion...
