That's great!!
Thanks brizzo!!

Well, since zxbdragon didn't say either yes or no and this is a hobby stuff that can help many people if properly RE'd, I'm sharing the relevant pictures.
Hope I'm not doing anything wrong.
All credits for these photos go to the zxbdragon, so, many thanks to him!

Nice, it's showing some promise. :-) I could convince him to take some more pictures: WhatsApp Image 2020-09-25 at 12.05.14 PM.jpeg WhatsApp Image 2020-09-25 at 12.05.14 PM (1).jpeg WhatsApp Image 2020-09-25 at 12.05.15 PM.jpeg WhatsApp Image 2020-09-25 at 12.05.15 PM (1).jpeg WhatsApp Image 2020-09...

Neo geo also uses db15 plugs right? Are there any neo geo light gun games? I have absolutely no idea. I'm trying to convince my friend to do some small tests with a multimeter and get some pictures of the board further disassembled. Unfortunately he's very afraid of not be able to put it back toget...

Do you know, with SRAM, you can put address lines and data lines in any order? :) ALWAYS you see special routing to keep them correct, nobody must realize it. That's great! I think these pirates had figured it out back on the day. They even "swapbinned" the PRG! :-D https://drive.google.com/file/d/...

Hello. A friend of mine bought a batch of old stuff. On this batch, there's this weird gamegun: WhatsApp Image 2020-09-22 at 7.00.58 PM.jpeg WhatsApp Image 2020-09-22 at 7.01.10 PM.jpeg Since it has this DB-15 plug, the first thing I tought was it could be a Famicon or Famiclone gun, but it didn't w...

O yeah! Glad to know it worked. :-) If I remember correctly, when I changed the broken FeRAM of that cartridge, I also used a 10K resistor as pull-up on the SRAM's /CE. I used this circuit, that's pretty similar if not exactly the same you described. There are some pictures of the fixed cartridge on...

As expected, such PCB like this one (glob MMC3 + two DIP28 mask-roms) havs some shuffled lines for anty-copy (this time: MMC3-PRG-A15 -> PRG-ROM-A16 MMC3-PRG-A16 -> PRG-ROM-A15 MMC3-CHR-A15 -> CHR-ROM-A16 MMC3-CHR-A16 -> CHR-ROM-A15 Great! That explains why I'm having trouble. That swapped A15 and ...

Krzysiobal made a schematic of a Sonic 3 a while ago here.
There are PCB p0rn pictures on the begining of that same thread.
Hope this can be usefull.

looks like the pirates also populated it with a real cap instead of the traces? It might have been an experiment they tried. Maybe they couldn't get the value large enough to work. It was me who put both capacitors when I was trying to fix the game, since it crashed and the HUD jumped a lot. The ju...

Hi. I've got an pirate The Punisher cartridge wich the PCB uses what seems to be a OR gate with a resistor and a diode, plus a PPU A12 deglitch capacitor printed on board. The OR gate works fine, no doubts, but any chances of this "printed capacitor" to work fine? Probably I can just figure it out b...

Hello. Recently I've got another pirate game, Robocop, wich uses as mapper an IC labeled as 9051. Pictures of the board: Assembled PCB: Robocop - Montado p.png Component side: Robocop - Componentes p.png Solder side: Robocop - Solda p.png The IPS with the ROM differences from Robocop (J): Robocop-Pi...

Unfurtunatelly I think that's not a good sign.
Does anyone knows if BootGod and his family are fine?
It they're OK, I insist that would be a good idea to mirror BootGod's site somewhere else.

I had some issues with a pirate MMC1 mapper that I discussed in this topic.
Not sure if the problem is related.
In my case it wasn't a chip, but an epoxy IC that some friends call it a "tick"!

WOW!!
Another impressive work!!
Please, keep going with this.

Aren't you the same guy who's porting Megaman X for the Mega Drive?
That's another really great port!
