Help adapter 29lv320 snes
(1/1)
SNESPCB1:
Hello everyone, could anyone help me understand this mx29lv320 adapter for snes pcb? No, I have no idea where the adapter pins are connected to the maskrom snes

I'm sorry, but could you help me with the jumpers for each pin that goes from the adapter to the snes maskrom? I'm a beginner and I don't understand anything, there are no diagrams on the internet, thank you
JRBVZ:
--- Цитата ---The Mask Rom must be “deactivated” as a final step. Do this AFTER the adapter has been mounted on the donor.
The MASK Rom has a control line, the “/OE” line. When this line is tied to 5volts, it deactivates the rom as if it was never there. The Control line is pin 33 and the 5volt line is pin 34 (how handy!) Cut pin 33 close to the pcb and then bend it over to the 5volt pin and solder. The Mask rom is now deactivated. Don’t let the MASK Roms confuse you…. There are 36pin and 32pin mask roms but the control line is always in the same place. Just Always count as if it was 36 pins.

Yes friend, thanks for the explanation, but what I really needed was the gerbers for this mx29lv320 adapter, because I want to have it manufactured so I can put the games in, I don't know where the adapter tracks are connected to the maskrom pins, and I would like it to be with the option of 4mb, 2mb and 1mb, if you can help me with the printed circle so I can understand it and also send its Gerbers for manufacturing as I only have this example photo
JRBVZ:
Так бы сразу и сказал, что у тебя нет адаптера. Вот Kicad проект: https://github.com/gaggi/3v3tsop48flash2maskrom
Но герберы я делать не буду ;) Изучай сам. И ставится этот адаптер спереди PCB, вместо maskrom.
SNESPCB1:
ha yes, it looks very interesting, I hope it works well, I'm going to download his Gerbers and test it on a SNES PCB, thank you very much friend for everything
