Thanks. Such conversions are nothing new though, they've been done before by RicBit (Girl's Garden, N-Sub) and MSXFiles (Bomb Jack, Mikie, Orguss, Dragon Wang, Star Jacker), as .com files. The only change here is it can be legally distributed.
(BiFi: before you might ask, if you want to add the IPS without other files (readme, source) to ips.tni.nl, you have my permission as long as you provide credit)
Deckard69: please visit http://www.romhacking.net/faq/ and read "What are patches?" and "How do I apply a patch(also known as 'Hard Patching')?". You actually don't need to patch the Sega SG-1000 game to make it run on blueMSX; blueMSX supports emulation of that console already :P
