Any interest in 27c322 cart mod pcb's?

[Markfrizb]

Well, I guess I had a bad rom burn. 8 in 1 works fine now with a new rom burn.

I think so long as there's only 1 game in the list that uses the SRAM, it should retain that data even if other games are played (unverified though)

I also made an addition to the design where you can have a 2in1 multigame that chooses between the 2 32mbit roms.

Theoretically, you could have a 16 in 1 (512k games) or a 8 in 1 (1mbit games) or a 4 in 1 (2mbit games) with the 2 roms.

Those boards look like a bit complex, don't they? I guess they took a hard time to desing, but... what are their purpose? Just to use 27C322 in a donor cart to make your own repro? If so, there are some other solutions cheaper and more "powerful" since you don't need donors. I made these boards to build repro carts up to 64 megs (HIROM) and 32 megs (LoROM):

I'd like to get a couple if your boards Magno. I wasn't aware that you sold yours to others.

I made this because I have a TON of donor carts laying around. And the multi-game aspect. And it's for the guy who wants to do a repo but doesn't have the skills other than soldering. Also, can your EPROMs go in sockets and cart shell still close? That was high on my list -- to not soldering roms in only to find out it was a bad burn. When I tried the 8 in 1 multi and had a bad rom (checked out as good), it would have sucked to desolder that monster. It was nice to pop it out and pop in a new one. The thing I like about this design is, it can be as simple as short 1 solder jumper and install the rom (assuming the 16 to 8 bit converter chips are already mounted). It can be configured through different jumper pads to to ExHiRom games or multi games of almost any size games including 32mbits X 2.
I may make a full cart next. I admit I'm not very knowledgable about the mad1 and a few other things. But as I make what I make, I learn more each time and apply my new found info to my next pcb design.

Magno, PM me please. I have a few questions about your board.

Thanks.

Ah, ok, both are good points XD My board is not multi-game, although I designed a different one that supports that (using 29F032 flash memories). And I can't mount the EPROM over a socket neither, since there is not room enough inside the cartridge. It's a good thing that you were succesful doing it!

Fell free to email me or PM me to ask whatever you want about my boards.

Could this do Zelda Ancient Stone Tablets, all 4 weeks?

QUESTION: do the 4 weeks all share the same sram data? IF all 4 weeks uses the same sram data, then yes, it will be able to do all 4 weeks. The prototype isn't set up for it but the final version will be able to. BUT, it would require hard soldering the roms to the adapter (no sockets).

Here is a new video of 2 x 32mbit roms being switched using the reset. So 4 roms would be the same way but with a different set of jumpers.

[josete2k]

Yes, all weeks/parts share the sram data.

[Markfrizb]

Yes, all weeks/parts share the sram data.

64kbit I assume? Lo rom model?

[josete2k]

Yes, LoRom and 64kb SRAM





He's using a pic12F629 instead the binary counter 393, so you can manage the bankswitching more accurate.

It's four different 4 megabyte ROMs. You'd need four 27c322s to do it.

Can someone point me the the bigger roms (or bigger + works on real hardware)?

This was what I found (2mByte file sizes, not 4)

The 4 megabyte versions are on the page too. No idea if they work on real hardware or not though.

I programmed the roms (x4) and mounted them to my adapter. The games all boot and cycle correctly. I'm not a Zelda player so if someone wants to test this cart for me, I'll send it to you.
MottZilla-- you interested? I'd like to determine if the 4mB x 4 version does work completely on real hardware so I'd like it to be tested ASAP.

I'll post a video soon of my progress and tests.

Thanks

The version I have are 4 files, 2 meg roms. Would that version not work on real hardware or something?

[Tormenter]

Yes, LoRom and 64kb SRAM

Where are those wires going to in the back? Do you have a pic of it? Thanks

Id be interested in trying it out.
