Here you have a teaser of the EnterMice adaptation for the SWAP game.
It seems to work, except the EXIT and music off buttons, that hang the game. To fix this will take me a little more time.
Inside the packet you have two executables, SWP.COM, the original game just as geco decrypted it, and SWP2.COM, my work-in-process. This is a modified loader that adds to the program the mouse code, contained on SWP.PR9.
Also I've included a more or less accurate disassembly, SWP.ASM, and the sources of my modifications, SWP2.SRC and SWP.PR9.SRC.
