i think you can just rename the extension to smd and they'll work. if there are too many files to do by hand use a batch file. create a new notepad document, open it up and write "rename *.bin *.smd" (without the speech marks) save it, rename from .txt to .bat, put it in the same folder as your roms and double click it.
alternatively, just download a romset in the correct format... they're very easy to find.
Renaming it won't work i tried that already. And as i stated earlier in my earlier post, almost 99 percent of all the sega genesis roms are in the bin format. I know all the popular rom websites, i already tried to download a few from them as well and its all bin. I have a cd rom that has all the sega genesis games, and 99 percent of all games were bin format.
The only way i would be able to get them in other formats, is if there is an international website like a european, or spanish or maybe brazililian website that has roms that might have the roms in smd format.
I even tried file sharing sites and they were in bin format. If you find anything, let me know.
If i install the official firmware for the gemei a330 thats in chinese that Yoshi put a link to, do you know if the sega games will run on bin format roms? Right now, i haven't installed the official firmware. I got my firmware from filetrip website because i wanted the firmware to be in english, so i can understand what the main menu is saying.
If i decided to install the official firmware thats in chinese, do i then go ahead and remove the filetrip firmware for gemei a330 or do i just keep it on the root menu as well?
Suppose i get the sega genesis roms to run on the official chinese version firmware, then what do i do? i don't understand chinese.
