Drmd - When Roms Go Bad

[ketchupgun]

Is there an exipry date on these ROMs?

I don't know why, but every so often, I have to replace ROMs (megadrive roms) as they stop working..which sucks cause the save states dont' work anymore.

I had all my "shit" togther and nicely working..
then I download Tony LaRussa Baseball...put it on the card.
Recaned the directory in DrMD
and I got some weird garbled text rom...I hit it..the GP2X froze.

I then rebooted.
started up DrMD...and now it works..or so I think. Some I my roms just leave my on a blank screen..so I have to replace them .. esp. Phantasy Star IV .. I replace it...now my save states don't show up...though they are still in the drmd/md directory.

and my old Flashback rom works...but the save states don't


anybody got a clue here?

Right, this sounds more like a memory problem than a rom one - roms don't have expiry dates, but if your files are becoming corrupt somehow, that would explain why they stop working after using them sometimes.

Are you using an SD card? If so, run a scandisk on it, see if anything shows up.

Try redownloading and reinstalling the Emulator first though, just in case.

The savestates system has changed since the last version of DrMdX.
And the savestates aren't compatibles.

yeah sounds like an sd card issue. Are you transferring your files using the gp2x usb connection? Don't do that, get a card reader. The usb connection might be screwing with your file system on the card. Maybe run a scandisk or checkdisk on the card. Or backup all files of the card and then format your sd.

ok .. sweet.
I just bought a 2GB card...put it in and started running things off it. Then I realized I didn't format the card. I backup up the Sd on my HD.

I'm on MacOSX so I wasn't sure what to do in order to format Fat32 (or whatever), so .. I debated formatting it as Unix (instend of Mac OS Extended) ... then I just formatted the SD in my Canon Powershot (perhaps stupid,l in retrospect) .. so now I got these problems, as I put my backups roms and files on the card.

I always use my PCMCIA card reader .. unless I'm out of options and use the USB connection (whihc I wasn't egtting with my unformmated card).

so now .. how to I best format this 2gig SD card on my Mac for this gp2x?
and if this solves my save state and ROM probelm, then I'm happier than a pig in "poo poo!"


(i don't mind re-downloading everything and starting from scratch if the new card will be ultimately formatted correctly)

Also, do you guys find it best to keep the roms ZIPPED if the appicaltion will accept it as such?

Just do a google search for "MacOSX formatting/format", and regarding zip files; there's hardly any difference. If it supports zips, go for it, it saves space and doesn't effect the game performance, but it might add a little extra load time depending on the rom size.

I own a Mac by myself and the best way to do that is just to start the "Disk Utility" application that's already installed on your mac and then just to format the whole thing as one partition in "MS-DOS ( Fat-16 )". If you'll encounter any problems after formatting it like that, it will be the software.

works great!

thx DaveN .. for the Mac spec. help!

I had this problem on the Zodiac with a certian 2GB card. Neogeo roms would randomly corrupt. Turned out the card was not 100% compatible with the Zod, although it did not show any signs of that...
