Yeah, I would have to take that into consideration. I would make sure that it would not modify any of the ROM in $A000-AFFF.

If that were to happen, you could run it on a VIC-20 with the cartridge version of the game (by plugging it in) or by downloading the .prg, saving it to disk or tape, and then loading it onto a VIC-20 with RAM expansion (that can be located in A000-AFFF) which the Mega-Cart would definitely support.
I will try as hard as possible to stay within the 3.5KB of VIC-20 memory however. I think that my making a cartridge-based RPG game would be more suited for something like "Realms of Quest III" (I would then make it a 16KB cart that resides in A000 and 6000).
My making of "Dunjon 3-D" will serve as a springboard to RQ3 (kind of like how Dunjon II's game engine eventually turned into RQ2).
