The .BIN extension is used very widely for many completely unrelated data types. It happens to be a very common extension for ROM images of many formats. In the context of Genesis ROM images, a .BIN file is a straight binary image of the cartridge ROM contents rather than, for example, a SMD image, which has an additional header and organizes the data in interleaved blocks (probably to optimize for the communication protocol on SMD copiers). You can load it directly into just about any Genesis emulator to play it, or if you need it to be in a different format e.g. for use on a copier there are tools that can convert between formats.
oh yeah, and i replyed to this same question in the ftp forum, without realizing it was posted here too. Please dont post the same question in more than one forum, and try to refrain from posting questions/requests in the ftp forum at all. Thanks.
okok ive been looking for .bin to .smd converters... but none of them make any sense... are there any simple ones out there... or one where someone could tell me the commands neccisary to convert my strider bin to an smd.
You shouldn't need to convert it to play it on any genesis emulator.
Edit: I just downloaded Gens 1.50 and it loads .BIN images without any kind of special procedure. Whatever your problem is, I doubt it has anything to do with the fact that the image is in .BIN format.
gens will play genesis roms in both .bin and .smd format, there is NO reason why it would play the rom in smd format, if it fails to play it in bin format, if it doesn't play the bin, the rom is fucked in the first place.
