^^Sometimes the FPGA mapper does not properly emulate the real mapper. Neither flashcart fully emulates MMC5. Castlevania III runs on the Everdrive but ROM City Rampage totally glitches out. The original supplied MMC3 Powerpak Mapper totally glitched out with Wario's Woods for instance. Loopy's mapper pak fixes this. Unzip the Loopy mappers over the v1.35b mappers from RetroUSB and that will give you pretty robust compatability with the vast majority of games. Krikzz provides regular updates for Everdrive N8 and these are at least as good. Could also be a bad or improperly formatted header or garbage appended to the end of the ROM that might screw with the Flash Drive but the emulator overlooks. Also some ROMs are too big. If either the PRG or CHR is larger than 512kbyte, the game will not work on either flashcart.

Oh man... i don't understand any of that shit. I bought the Everdrive N8 and the mini-sd from a guy that had already set it up so that i only needed to add the roms in the right map. I guess i'll just have to skip what doesn't work wich is pretty sad.

File fragmentation or corrupt / outdated mappers may also be suspect. Reformat the SD Card using Windows, using FAT 32 with 32kbyte sector size. Make sure the SD card is between 4-32 Gigabytes SDHC. Go to krikzz.com and download the zip containing the most recent mappers and OS for Everdrive N8. Follow the instructions and unzip to the appropriate directory. Collect all the ROMs you want to use and arrange them into folders on your PC. If you are using complete ROM sets, they need to be unzipped and arranged into folders with a maximum of 252 ROMs per directory. Any more than that and Everdrive won't read them all. I recommend "No Intro" if you go that route as it purges all the bad dumps, hacks, and alternates which you don't want sitting on your flash cart. Preferably arrange the ROMs alphabetically. Common letters like M and S will need to be split to avoid the 252 file limit. Rare letters like UVW or XYZ can be combined if you want. Add any homebrews, hacks, or translations you want to try out in a separate folder. Least that's how I do it. Once you have everything arranged exactly how you want, copy the entire directory to the SD card using Windows. Starting fresh will prevent file fragmentation which may cause errors with otherwise working ROMs. Hope this helps. Follow the steps outlined above and any games with supported mappers (ie 98% of US released games and a large majority of non-pirate, non-bootleg Famicom games) should run fine. MMC5 is mostly broken except for Castlevania III.

what we need is someone to build an NSF player cart, that only does nsf, and uses cf card or sd cards.
Max file size that does 1mb or higher
Can use all 6 types of expansion audio, and up to six multi chips. That would be very awesome of an idea!

Just got my SD2SNES Ref F. today in the mail and, for the most part, am enjoying it a lot. I've had some issues with a few roms though and was wondering if you guys could help me out. I'm running the 0.1.6 firmware from krikzz's website along with the dsp BINS and other files from stone age gamer.

Here's the issue I've had so far:

Hagane: gets to the start screen but when I press a button the start screen glitches out and game hangs
Super Castlevania IV: game starts normally but after the intro where you see Belmont crack his whip the game never starts
Mega Man X & X3 - Graphical glitches on menu, won't play
Aladdin - Glitch and hang on menu

I've tried two different Hagane roms and both have the same issue. Any ideas? Is there a set of ROMS that is preferred here for use?

Thanks!
