This ColecoVision emulator is very exciting for those of us that played the system when it came out in the early eighties. ZX-81 ported the emulator from the Unix version that was made by Marat Fayzullin. It is for 2.5 PSP firmware, but should also work on other firmwares. A 1.5 binary is included (kxploit). This is a beta release, source is included and it was released under GPL. Read the included text file for instructions and more information.
