Yea some can be reflashed, for the gameboy a simple gb programmer, you can make one yourself.
For the gba botlegs i'm currently working on a programmer, gba botlegs can be reprogrammed with the parallel cable that was include in the firelinker 128m.
Non volatil game boy saves (done on Pokemon Yellow, but problem on Pokemon Gold)

so not sure if I look for a flasheable bootleg, the GB "memory" or mod one cart myself/ask someone for doing it? xD
This GB programmer could work for gba with the program? maybe not?
I heard about an USB-GBA cable that could reprogram the bootleg, and looks like we could not DIY it...
I'm wanting to do all he stuff but I have no idea where to start XD
Can't we use an DS/DSlite to do the job? the EZFlah 3in1 had a way to send the rom to it, maybe a homebrew could do the job (for GB/C games maybe work, but it would need to put the circuit there without the case? hahah)
You can make one your own but you need some soldering skills, i don't mind making one for you but i need a cartridge, if you want the clock feature you need a pokemon one.
Where did you hear that ?
Didn't find anything
well I have a bit that I'm not that trustful (but I saved a crazy "corroded" N64 controler XD McGuiver must be proud!) haha I heard that the "GB Memory" the board have a place for the clock thing ... but anyway depending your price we can see what we can do o3o
was in a post about re flashing an zelda minish cap bootleg that come with a save problem
The cable was from a flahscard that the one you told, but instead of parallel port, was by the USB
Edit: Found it (at least wich was)
Flash2Advance USB linker
about this cart?Didn't find anything
here:
https://gbatemp.net/threads/beginners-guide-to-the-ez-flash-3in1.293643/
but well, this cart was made to work like this xD but I've never tried this GBAexplorer with a bootleg (because I'm without a DSlite at the moment :v )

GB Memory ?
That cable can't be find for sell on internet. A shame.
Do you have the link of that topic ?
I know this cart, what i mean is that i didn't find any homebrew for flashing a gba botleg.
GBAexplorer will work only with the ez flash 3in1.

what's the conclusion about this project?
can we finally mod original cartridges of pokemon gen 1 and 2 with non volatile memory?
can i purchase pre modded games from any of you?
are theese games working with poke stadium? what about super game boy mode in the first gen?
there was a kinda similar project that was putting a battery holder compartment to easily swap the batteries, but used smaller ones which are more cheaper..
but replacing the s-ram would be even better...

Looks like yea but you won't get the clock function or you must leave the battery.
I don't have any games but i can do it for you if you want a game with a fram chip. I will need the name of your games though
pokemon stadium ?? super gameboy mode ??
I never got around to debugging the GS glitching (unless it was just the RTC, in which case you can still swap the RAM, just keep the battery too, if it dies the clock stops but you won't lose your save). What I CAN say for sure is that Gen 1 works.

that's obvious...
my point is to prevent save losing.. however the easily swapable battery holder mod + backup tool is another solution i am thinking..
or, :why not both: mod the cartridge both with the F-RAM chip and easily swapable battery, when clock battery dies, save is not lost, replace battery clock working again
yeah, it was kinda mentioned in previous posts that doing this non volatile f-ram mod will prevent the cartridge from working with pokemon stadium (n64 transfer pack) which is a big bummer
by super game boy mode i mean, will the cartridge work without issues in color in a snes ? it was also mentioned some sprites corruption in other games, kinda worried this mod will glitch in super game boy mode

this thing
yeah :/ I don't find the topic yet but if I do, I send you
but there wasn't much info more than saying it's was possible, if I'm correct
oh right xD yes I know nobody did(or made public), just speculating if is possible.
I think is about it not having problem (working like oficial) when linking to Pokestadium and snes GB player
Sorry, I hadn't really kept up on this thread so I missed that part. It sounds like what has to happen is to add the logic on the /CS pin. There's one option listed earlier in this thread, but the one once used instead on SNES games instead is CS_OUT = CS OR (RD AND WR) which can also be done with a quad NAND, i.e. CS_OUT = (CS NAND CS) NAND (RD NAND WR). The wiring is likely to be tricky, unfortunately...

oh I found this , but was also kinda of a request:Didn't find anything
https://gbatemp.net/threads/reflashing-bootleg-gba-games.469792/
Would it be possible to make the FM18W08 work for MBC3 cartridges using this added logic?
!(WR AND RD) AND A15 = FRAM CE
We know ROM is enabled on A15.
We know ROM shares the bus with RAM.
So, as long as a read or write is taking place, and it is NOT the rom, it should be the ram? We could then maybe OR the read and write signals, then AND that with the inverse of A15? Finally, invert it because CE of FM18W08 is active low.
I'm really sorry to bump this thread after all this time, but I have invested a lot of time and money to this project, and I think I'm very close to finishing it. I have made a couple prototype flash cartridges with MBC3 and FRAM, and everything works except communicating with my FRAM chip. See for yourself in the attached pictures.

Hi, thanks for all, I need some help,
The conclusion that i want to apply to my games are:
Zelda Dx/Pk red and blue FmFM18W08
Pkmn crystal FM28v020
Zelda Oracle of ages/seasons FM16W08
This chips are allright for this games?
Whats the diferences between soic And a sop chip?

I won't be able to tell you if it will work but you can give it a try, I've checked the pins and size compability, if it doesn't work or there is some glitch then connect the Vdd pin and CE pin with a 10K resistor.
Same pin spacing for SOP AND SOIC but SOIC got a wider package. Check their datasheets for more info.
Hey guys, sorry for bumping this thread, but I think I just cracked the case.
The FM18W08 is the chip you want, should work on any cartridge that has SRAM.
If you are using MBC3, connect the FRAM CE pin directly to the cart CS pin (pin 5) instead of the RAMCS pin on the MBC3. Leave the RAMCS pin on the MBC3 disconnected.
If you are using MBC5, this chip can be used as a drop-in replacement with no additional work.
ONLY ON MBC5:
The power-down chip can be removed if you place a 10K resistor between the Vcc and CE pin of the FRAM.
EDIT: Unfortunately this method only works for Gameboy Color, not DMG. Games on the DMG do not boot if RAM isn't connected to the MBC3 RAMCS pin. I have a feeling it has to do with the GBC running at 2x the speed, but I can't say for certain. This will take more work to figure out.
