I looked into it, but it would cost me more than just buying a Pokemon cart and burning the chip.if you want to make a gbc flash cart so you can play roms on you gameboy wouldn't it be easier to buy a EMS USB 64MB GBC flash cart?

Nobody has called you stupid once before you pulled out the numbnuts on us. There were no bullshit responses either - I wanted to establish whether the cartridge even had those features in the first place and they were removed or if you wanted to add them. We wanted to know what you're trying to do to best assist you.I never said I knew more, I just won't take bullshit responses. If you're going to explain something to someone who is still learning, don't go "well you're just stupid". I know my shit, and I've researched a lot before I went and bought a cart. I didn't realize it was going to be missing a battery. Boo-hoo, I must be a kid because I didn't get a proper explanation when I asked.
And now that we have estabolished it won't work, I have been considering getting a custom board.

What you're trying to do is physically impossible - you cannot rewrite the ROM, you have to swap the chip for a rewrittable one and you will require a compatible MBC revision if you count on any compatibility whatsoever. You will not reach full compatibility due to various Bank setups the Game Boy used, but with the schematics I posted you'll get the best compatibility there is. If you are really dedicated, get one of the listed games, one of the listed chips and start soldering.

The cart I have has MBC5.
Well, the obvious difference between MBC3 and MBC5 is MBC5 is missing clock/timer. I could just ditch it, since it's not really necessary. I mean, my mod will include everything at a certain daytime. I could just route the data elsewhere.what would happen if you address non-existing physical area (burned on the MBC?) and/or the game issues MBC commands that are not available on MBC5?
PIC burners.
But no worries, I was only looking for someone to explain this to me.
Alright.PIC burners are used to write instructions into PIC microcontrollers which have the capability to be written into, you cannot flash a chip which does not have this capability. Once a ROM chip has been filled with data, that's it, done. I apologize if you felt offended at any point, I'm not here to argue with you, I'm here to explain things to you.
If you want to achieve what you are trying to achieve, you will need a cartridge with a compatible MBC setup (5 is the most compatible of all), SRAM, a battery and a compatible ROM chip that you can replace the original with. No other method will work, otherwise people wouldn't bother with soldering 20-odd wires to their boards.
Alright.
I read up that an EPROM was used on a GBC cart, a 1:1 match.
That's probably the flash chip you mentioned, which has the matching pinouts.
*Glances at the photo, doesn't see a window, sincerely doubts that you have a flippin' mercury-vapor light source*An EPROM (rarely EROM), or erasable programmable read only memory, is a type of memory chip that retains its data when its power supply is switched off. In other words, it is non-volatile. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source (such as from a mercury-vapor light). EPROMs are easily recognizable by the transparent fused quartz window in the top of the package, through which the silicon chip is visible, and which permits exposure to UV light during erasing.

...good luck?
Just use a dremel to grind the top off and put some clear cellophane wrap on it
...and then send it onto the surface of the sun instead of, y'know, replacing it with rewrittable flash like everybody else. ;O;
...or he could build a mercury-vapor lamp... and get mercury poisoning in the process. ;O;
...I also have a feeling that he might damage the actual chip if he's never used a dremel to de-surface a chip before. Just a hunch.
It's possible if you're extremely gentle and precise - it has been done with more delicate circuitry, it can be done with this. I just don't know if the OP realizes that UV erasing is something he will have to perform every single time he changes the ROM image... or that it causes wear and tear... or that keeping the chip under the light for too long will damage it... or that keeping it under the light not long enough will cause false writes... Or that erasing itself will gradually lower access times regardless of whether he does it right or wrong...You might want to go to a chiropractor if you have a hunch... poor posture is no joke.
(Also I have no idea if desurfacing the IC with a dremel/sander/anything like that would be a good/feasible idea or even possible period. I sure as hell am not trying XD)
And I've been considering making a custom cart, seeing as the wires go.... differently. I will be looking into getting a custom cart, maybe. The wires from the ROM remain the same, but the MBC5 baffles me compared to other carts. I might research it later, I dunno.
I think this was an educational $6 piece.
The reason I was looking at the MBC was how it looks like it connects to the SRAM in this picture:To be 100% fair, you can mod this cartridge to work with other games, but you will not be able to save or use a clock simply because the cartridge does not support that. Leave the MBC alone and focus on the chip (CGB-AOXE-0) on the side, that's what you're interested in.
