EverDrive GB / Re: Everdrive gb x3 Fat error
« on: August 25, 2019, 11:34 AM »
The recent game list is just a list you can use to load games you have played recently. I believe you can purge it by deleting a file in the system folder or something. Not all Everdrives has this feature though (my EDGB doesn't).

The Everdrives may also store things like cheat codes or save type settings for each rom. Save type wouldn't apply for Game Boy since there are only one type of save memory (battery SRAM), but N64 and GBA games do use various types of save memory.

If the Everdrive GB both have a .SAV and a .SRM file I would guess that the SRM is the game's own save file (battery SRAM) and the SAV stores either the above-mentioned settings or save states.


If this FAT error happens because you have deleted files and have some kind of save files that no longer has a matching rom, the FAT error should go away if you just backup all roms and save files (skipping any unused/unneeded save files), reformat the SD-card and then put a new copy of the latest OS (redownload it or uncompress it again if you already have the archive file) and also restore the backed up roms and save files in their respective folders.

It's not the save files. It just seems that everdrives like to create a back up of any rom you play which is hard to remember it does that. So lets say you decide to play a Gameboy rom like Mario Land despite it not having a save feature the device will always remember your previous settings.
I have no idea what you are talking about. You say it backups the roms (this has never happened to me) and not the save files? Then you talk about remembering settings, so you DO talk about some kind of save file after all?

I just tried loading Super Mario Land on my EDGB (the pre-X-series Everdrive) and then I power-cycled and loaded Tetris. No save files or any other files was created by doing this, since Super Mario Land is marked as a game that does not use battery backup RAM. All my other Everdrives also works like this.

Emulators like Goomba may make save files for each game to store save data, save state data and emulator settings or so in. But the Everdrive itself should not create save files for games that doesn't save.

What is weird however is NEG Geo Pocket and PC Engine roms do not make sram but as said above it is likely due to the fact they are merged into a in game folder which has multiple games on a single rom so they do not take up space.
It might be because PC Engine doesn't save to the cartridge (with two exceptions), but to the internal memory or by using passwords. NEG Geo Pocket also has internal memory but I think games uses battery-backed SRAM or EEPROM for saving. Maybe the emulator is just crappy and doesn't support saving.

Hmm? What's the difference between SRM and SAV files? From what I remember the Everdrive just saves a raw dump of the SRAM, so there are no special formats. For GBA it may be different because games uses battery-backed SRAM, EEPROM or flash to save. But for Game Boy pretty much every game uses battery-backed SRAM (maybe there are a few exceptions, I don't know).

In my experience the Everdrive does not keep the SRAM dump of games that doesn't have a battery (there is a flag in the rom header for battery that the Everdrive probably checks). I don't know about emulators though.
I have the original EDGB, not the X-series so there might be some differences.

I didn't know the Everdrives has a limit how many save files they can handle, but yes if you for some reason have a ridiculous amount of save files and the Everdrive doesn't work as expected anymore. I guess the solution is to backup all files you want to keep, reformat the SD card and then copy back files to the card again, but not too many save files. Also report the problem to Krikzz.

I think i was realy confused because i read the word "save ram" or "save" in descriptions of the everdrive X5.
That descriptions just meant to say that the X3, X5 and X7 (but not the old Everdrive GB) all supports saving in games using up to 128KB save RAM. That should cover saving in most, if not all official games for Game Boy and Game Boy Color that can save.

I heard somewhere that, possibly due to a bug in the firmware, 128KB saving doesn't really work on the Everdrives. Krikzz might have fixed it by now though.

OK that explains why you where confused. I don't know what gave you the idea that the Everdrive could save the state automatically or via a special button, but if it could, that would be a type of "save state" feature (what's the difference between saving during gameplay and automatically saving when turning off anyway?). Something you knew it's incapable of. That's why I was confused why you were confused.

So the save option has to be an option in the game itself? Or what do you mean with "you need to save inside the game first for this to work"??? Most of the old gameboy games only have a password option and no save option.
Yes of course you need to save in the game itself. Isn't that what I've been saying all this time? You said you understood that the Everdrive doesn't have a save state feature so the only way to save is using the games own save RAM feature. If the game uses passwords or doesn't have any way to save at all, we don't even have a problem in the first place.

You understand that the X5 don't have a save state feature and yet you are looking for one? You don't need to do anything special to save to the save RAM, except for saving in the game itself.

Save RAM is the writeable potion of a cartridge that games uses to save. The Everdrives has this too so that games are able to save like normal. You don't need a menu to access it because only games needs to access it, not the Everdrive. If you play a game on the Everdrive, the game will save to the save RAM. Your "save" folder in GBCSYS will remain empty as long as you don't play any other games. If you decide to play another game however, the Everdrive will copy the save to the "save" folder on your SD card so that the save RAM is free to be used by that other game you loaded up. If the "save" folder is still empty even though you loaded several games, something might be wrong, or the games you played simply never saved. Not all games can save.

If you play the same game for a very long time you might want to start up a different game once in a while so that the save is copied to the SD card, and then copy all your save files to your computer for safe backup.

Pretty much all Everdrives works like this, even the X7. It's just that the X7 also additionally have a save state feature. Everdrives without a battery, like the X3, requires you to reset before turning off so that it can copy the save to the SD card.

With "no country" i meant the file name. For example: Tetrix (USA) is only Tetrix. I donĀ“t have any roms with same file names.
That's fine as long as you know what game you are playing.

EverDrive 64 / Re: NTSC/Pal switch
« on: August 07, 2019, 02:04 PM »
No it's for setting the Ultra CIC to the region of your console, not the region of the game you play. You only need to flip it when you play your ED64 on a different region console.

News / Re: EDN8 OS v20-BETA. Large update incoming
« on: August 05, 2019, 01:14 PM »
Deleting files on the SD card causes fragmentation which the Everdrives may have problems with. But I don't reformat the SD card every time I do small changes like update the OS, only if something stops working (which have yet to happen on any of my Everdrives).

wow that would be awesome, nuu ? did you test this? :)
No I didn't know about it as it's not in the OS directory and no news note on it. It seems to be in the "var" directory on the download page. If it is what people think it is, it's great and one of the things I've wanted on many flashcarts! One thing I like about the Everdrives is that Krikzz listens to his customers! :)

SD2SNES / Re: Bug: 1-Chip transient fix brightness issue/blinking
« on: August 05, 2019, 12:50 PM »
As I understand it the 1-CHIP transient fix is an experimental hack for 1-CHIP systems that have trouble showing the air-plane shadow in Air Strike Patrol (or certain effects in other games using a similar technique) like the Jr seems to have. If your 1-CHIP system shows the shadow, you should probably turn this hack off when playing. Just in case you didn't know.

Then what do you mean by REV. H? Revision H of an unknown clone? I don't get it.

EverDrive GB / Re: Problem with x7 rev A saves
« on: August 02, 2019, 12:26 PM »
It is. Both the save RAM and RTC uses the same battery.
Try using no-intro roms if you aren't already.

X5 should have a battery for the save RAM so no need to reset. Maybe the battery is bad though. The roms might also be bad. Look for the no-intro romset if you don't have them already.

All my roms have no Country in the title.
What do you mean by this? The file names can be anything (using legal characters like ASCII), although you shouldn't have two roms with the same name. Also for your own sanity you may want to have file names so you know what version each game is (country code, revision number and in case of a patched rom, the name of the hack). No-intro roms already have a standard for naming of the files which includes country code and revision number for revised versions of roms, and no hacked, over-dumped or badly dumped roms are included (although the no-intro dumping group also makes mistakes sometimes).

How do you know it's a clone? I can only see the controller in the video isn't original.
