Yeah in fact I though of that and it would be cool if Enders game would be converted to it, but games like Reuben Quest would be impossible to port to BASIC builder for the following reasons:
1) BASIC Builder doesnt know if a program need to be archived or not when starting the app, so it puts them in the RAM. Most reuben files goes in the archive
2) We cannot use more than 26 picvtures, however Reuben has over 30
3) the code needs to be modded a bit (pictures) to be compatible, which would be very long and buggy due to the fact most pics are run from ASM utilities and the game is very huge.
