BugsThe ROMs for the game Joust in this release contain the "green" ROM image. The green ROM fixes a well known bug that allowed you to endlessly kill Pterodactyls on certain levels, thus achieving incredible scores. In the links section for this game you can find information and a patch program to undo the "green" fix and convert your ROM image back to "yellow" and take advantage of the bug!
OptimizationJeff Vavasour optimized as much as humanly possible with this emulator; the specs say that a 486 is the bare minimum, but you can play the Robotron emulator on a 386/33 and have very minimal slowdown.
