Do I just solder a ROM chip on and not solder an MBC chip to use it for a 32KB ROM? Or do I need to solder something else on? I'm not sure. I was looking at this one, but it shows that it has spacing set up for an MBC chip which confuses me and the readme doesn't address it so I'm at a loss as to how to handle this one.
Instead, they sell pre-assembled cartridges with their own designed boards at the exact price I was hoping to sell my game at (so buying their cartridges isn't an option without selling my game at a price above what I intended.) Both of these chips have been discontinued for some time, so I am unable to purchase them (at least not at the price of comparable chips that are currently available.) I don't want to just ask "what are suitable replacements for these chips" as a Google search will sometimes yield suitable chips (though those are often discontinued as well,) I would rather learn what makes these chips suitable so I can locate replacements on my own (and pick out larger chips when I make games that require a memory bank controller.)Īs long as I pick out a suitable flasher for my potential chip, do I just need to match specific specifications with the intended chip (memory capacity, minimum voltage, maximum voltage, etc.) to find a replacement? Or are there other factors I need to consider?Īs for the board itself, I've seen one or two boards I would like to use, but the creators don't provide files. The two boards I was looking at called for an SST27VF256 in a 28 pin DIP casing while another called for an AT49F040 in a PLCC32 casing. I'm trying to keep this cheap as I want to, hopefully, sell these cartridges for about $10.
I know how to solder, but I know nothing about designing PCBs or choosing what chips to solder onto said PCB. I'm looking to assemble these in bulk because I plan to sell physical cartridges at conventions and start an online store of my homebrew games. I was hoping to ask if anyone had a more recent flashcart design. The problem is that I can't find any Gerber files (which I can send off for production easily) that don't call for a specific chip which has been discontinued for years.
The game easily fits within a 32KB ROM file and doesn't utilize save functions, so I should be able to get away with a single chip board. I'm planning to port the game I'm working on to a physical cartridge once I have completed it.
