A super cap would be OK... I did buy a few a while back.. but never tested them at all. The NI-MH battery was charged at around 3.6V What i need to do is get a REV 14 out.. and do battery testing on that! Since its a factory coin cell setup. I think a rev 14 only powers 1 of the sram.. not all 4...

The original NI-MH battery is mainly for the "Book Keeping" features in the PGM. Its also made to be in a Arcade like setting. So if the game is powered up from like monday to friday and off during the weekends as an example.. the NI-MH battery would be fine. There is 2 ideas i'm looking at...

The coin cell has no where near the capacity of the original Ni-MH cell. Having said that.. the REV 14 has a coin cell from factory. I think i remember that the Rev 14 only powers 1 chip for the sram saves. But any revision before that powers all 4 chips. That could be why a coin cell doesn't...

I do... But its NOT great quality like the rest of my scans. https://igspgm.com/pcb/the_gladiator_road_of_the_sword/TG-LABEL.jpg I thought i had a 2nd Gladiator cart here... i might be able to find and scan it if its in better condition. You will find a lot of PGM stuff on my web site. T.

My last Test Print of @nnap help to improve the PGM shells. All is perfect! I use the shells with the M3 x 30 bolt to hold them together. It was a lot of fiddling to get them just right.. but its all perfectly fitting together now.

Yes. I have seen the cave carts do weird stuff if you have a battery onboard. I don't think i had dip 8 set on (but that might not make a differance) . But i was testing some carts and one had no sound and something else i don't remember. In the end i found out something in the sram left by the...

Sometimes you can get crap in the battery back sram that makes carts do stupid stuff. Remove the coin cell. Let it sit for a bit.. then try again. I have also seen faulty dip switches where they get stuck ON as well.. even after you move them to the off position. Other than that.. i'd try to get...

I have spine scans of almost every cart on my website! I have put in a lot of time , effort and money to share these with everyone. If you find something i don't have, Please let me know.

That fine having that voltage there.

PGM Motherboard Charging Circuit disable. All you have to do is remove R28 Parts side (REV 8 to REV 12) (REV14 Already has a proper CR2032 from factory. R13 does NOT exsist) OR R24 on a REV1 to REV 7. Then just fit a normal CR2032 holder where the NI-MH battery was. Simple! :-) Tim.

Some carts like Demon Front don't have the R1 100R resistor. I presume that's due to the asic chip being used as a CPU. Not sure if the other carts that use the asic as a CPU also have no R1 100R

The files you just uploaded... are they the same ones you sent me??

They look awesome! I'll do more work on the cases over christmas i think... i need some time to do more prints and tweek my printers settings....

You don't need a switch to change between black and white label if thats what your trying to do with DDP.... @iq_132 Already made a program rom with the original menu that lets you select which one you want to play.

Which Resistor pack are you trying to replace?? (On the PGM)
