Hacking New Theme for EZ-Flash Omega!

[Alacres]

are you restarting the system after exiting the game? are you just copying the new kernel to your sdcard, or flashing the new kernel by holding R during power on of the system to flash the new kernel as well?

Sorry for the delay. Yep, I restart it, it gives me the prompt to save the data to SD, and it normally always works. I was fortunate that I had a save state backup for this particular game (Harvest Moon: FoMT), although I still lost about 4 hours of progress, give or take. One thing I noticed was that it's not even letting me save in-game anymore, so I'm guessing I'll need to delete the save file to do that again. For now, I'm relying entirely on the save state function built into EZ. For future reference, is there a way to repair a corrupt save?

As for whether I flashed the new firmware, I'm pretty sure I followed all the instructions when I installed it but it's been quite awhile. I mean, it shows the "Simple" logo with the version number, and all the options are present. Would it do that if it weren't flashed? I guess I could try getting the very latest version and doing it again, assuming I don't lose any data from it.

Thanks, by the way!

@LukewarmTea Classic NES Series used multiple tricks to fool flashcarts and emulators, and one of these was setting the wrong save type in the header. Most games used SRAM, but these cartridges actually used EEPROM, and if the game was able to successfully perform an SRAM write, it would know it's pirated. Try setting the save type to EEPROM and see if that works.

No real clue why specifically Classic NES Series used various accuracy checks like this (trust me, some of them do crazy things), especially since the first known working Famicom emulator was released in 1990, and NESticle was already a popular project by this time. None of this would have helped fight NES piracy in any way.

endrift, in her 2014 article, explains that Classic NES/Famicom Mini titles use six different tricks. Since she was working on mGBA, probably most of them aren't an issue for flashcarts on original hardware (AGB, AGS, OXY, NTR, USG and DOL-017).

• Trick #1: Memory mirroring
• Trick #2: Code in VRAM
• Trick #3: STM to DMA registers
• Trick #4: Save type masquerading
• Trick #5: Prefetch abuse
• Trick #6: Audio FIFO irregularities

The implementation of fixes shouldn't be difficult according to other devs I've discussed with.

Any of them should be fine

I see lot of persons have some problems with save on simple 3.7 (no 3.45 ?) and i need saves not disappear every day

Just use the latest SimpleLight version. And if you still feel uncertain, enable the backup function, and wait 5 to 10 seconds every time you save the game and you are about to turn off the console, or just every time you're about to turn off the console.

This is a flaw with the hardware of the original Omega that cannot be fixed. The workaround is to wait for a few seconds after the save behavior of your game before turning off the system. The backup feature is a crutch in case things go wrong.

So why save disparition bug is reported on lasts firm versions and no before or on stock ?
Its not just a material problem or ?

1. It does happen on stock. EZ-Flash knew about the issue and couldn't do anything until the Definitive Edition because it's a problem with the logic programmed into the FPGA.
2. Yes, if you wait a few seconds after saving, you should be fine.

Progress update on Superdark DE
fixed some icon issues
updated the ui
added all the fixes from @TechieSaru & @Sterophonick
huge thx to @TechieSaru & @Sterophonick

gba nes classic roms work now with the patch from @TechieSaru
you have to set the save type to sram, and they work just fine.

NO. Do NOT do this. They are set to be detected as eeprom and then automatically re-adjusted to sram for the sake of outputting the correct file size. Just use the auto-detect for save type and they'll work fine.

ok nvm it works that way lol I was wrong

 

[TechieSaru]

well the issue is they don't load at all otherwise

They're not working with the save type set as auto detect?

no everything seems to be working fine. I believe my previous issue was bad roms

Ok. Good. This should work for both the proper 1MB dumps and the 4MB overdumps.
