EverDrive GBA / Unable to run Sega Smash Pack?
« on: July 25, 2020, 01:23 AM »
Has anyone else ever tried running the Sega Smash Pack USA rom?

The main menu loads fine, but the games don't work. Golden Axe looks like a mad seizure of sprites, and Ecco won't even boot.

At first I thought the ROM I had was maybe a bad dump, but it works in emulators and on my DSLite via a 3-in-1. I ripped my retail cart but it has the same issues.

I figured as a cart without any save it would be a shoe-in for working properly.


The EverDrive correctly identifies the save type as EEPROM, but the auto-patching doesn't seem to work. I know I'm not the first person on this forum to have issues with this game not saving.

Manually SRAM patching the ROM with GBATA fixes it.

Now I can finally continue the progress I made on my old EZ-FLASH IV!

EverDrive GB / Boot straight to game in GBX?
« on: July 09, 2018, 11:26 PM »
I know on the EverDrive GB, if you removed the sd card, the last loaded game would boot automatically.

Is there a way on the GBX to automatically launch the last loaded game without loading the ED menu and rebooting?

EverDrive GB / EverDrive GB X5 works on my Game Boy Light
« on: July 06, 2018, 08:29 PM »
I know that the first revision of the EverDrive GBXs had issues being powered by the GBP's 2xAAA, more so if you have a backlight mod. I've also noticed that when I play on my front-lit modded GBC the light goes out sometimes when loading a new game.

So I don't know if anyone's already tested it (I couldn't find any answers) but I just got a Game Boy Light, and the EverDrive works flawlessly. I can confirm that I'm able to boot, flash, and play my EverDrive GBX5 with the light on with no problems whatsoever, no flickering, or what have you, on not even fresh 2xAA alkalines.

I'm also on the first revision before krikzz fixed the power issue for GBP users, so I imagine it'd work even better with the recent revision.

Just an FYI for the next person trying to find answers.

Off Topic / RomSort - organize ROMs into alphabetical folders
« on: June 23, 2018, 03:51 AM »
If you're like me, and prefer to keep your ROMs in alphabetical subfolders, I made a tool that can do it for you.

Of primary interest to EverDrive owners, you can specify the max number of folders, and the tool will automatically combine folders togrther for you. That way you can fit all of them on one screen without having to change pages.

EverDrive GB / Everdrive GBX5 not loading all saves made on EverdriveGB
« on: September 17, 2017, 08:10 AM »
I've just got a new EverdriveGBX5 and a couple game saves aren't working.

I'm using the same SD card that I was using in my EverdriveGB, and all I did was add the GBCSYS folder and copy the SAVE folder out of EDGB and into GBCSYS.

All of the files have a .srm extension, and most of the save games loaded up properly in the GBX5.

I'm having trouble with two games:, F-1 Race and Shantae. Both started without showing my save, and both created a new files in the SAVE folder when I switched to another rom. The folder now looks like this:

SAVE\F-1 Race.srm (the original, 32kb)
SAVE\F-1 Race.SRM (8kb)
SAVE\Shantae.srm (the original, 32kb)
SAVE\Shantae..SRM (8kb (notice the double ..)

Looking on my PC, I can't delete the new 8kb files, in explorer or in the command line, I get errors that the files don't exist. I've run disk check/repair and nothing. I can't even delete the SAVE folder because it says the files that don't exist can't be deleted. I've even reformatted the disk and recopied from a backup to start over and I ended up in the same situation.

As a test, I loaded the rom (without starting) and then manually loaded the original save files into SRAM, and voila, my saves appeared in both games. I also played ahead in each game, and my new progress still gets saved as I switched between games.

I assume the new progress is being saved in these 8kb files, however, I can't open them or back them up. Opening the original files in a hex editor, it's obvious that they're barely using 512 bytes, let alone 8kb or 32 kb. I can verify that the original files aren't being updated as they still match my old backups and do not have the new progress. I can also verify that if I manually save the SRAM to a new file, and open it up in a hex editor, the new file does have the new progress.

Is it possible that there's a bug in the FAT LFN support? The only thing I can think of is that I rename all of my roms to remove all of the romset tags, and both F-1 Race and Shantae are shorter than the old 8+3 filenames.

I want to both continue my in-progress games and both be confident that they'll save properly and that I'll be able to backup the saves.

Tomorrow I'll see if making the names longer helps.
