I meant that the annoying part is the board, not the ROM. I don't mind using old/used EPROMs in this case, it's going to be better than this wonky pirate board that I have now. It doesn't look like it was hard gold and I think the fingers oxidized in a way that no amount of cleaning is going to brin...

Thanks for the tip, I didn't realize that. I guess I have nothing to loose if I destroy it with heat.

Annoying, this game is 16 Mb HiROM. The only HiROM boards for sale that I know of use 16-bit memory and SRAM. Does anyone make/sell a simple HiROM board?

Ah, perfect, thanks. I didn't realize that No-Intro records the model number of hardware like that. I suppose the box and manual could be really good quality knock offs, it's hard to say without a side by side comparison of the real thing. But even the plastic tray box insert is dead-on, I didn't re...

So I bought this Captain Commando SFC game about 10-15 years ago. It included the cart, manual and box. Nothing about the sale seemed suspect. I tested the game back when I got it and everything seemed fine. This wasn't a pricey game back then, I think I paid $20 or $25 for it and I remember that be...

I don't mind castellated vias because they're easy to solder and you can visual verify a good connection. But soldering through vias to pads underneath them, I don't know if there's a special name for this, but I very much dislike it! Have you ever spent more time than you care to admit trying to fi...

Unfortunately in that picture, they're still using 3V flash without protection on it , and the EPM7032 doesn't have enough pins (36 I/O) to be protecting all of the flash I/O lines (8 data + 22 address (4MB flash) + 3 control). I can't believe how many carts are being sold at retail that don't use ...

Out of curiosity, why not just use a level shifting IC? I know the 74 logic and resistors are very cheap, but wouldn't you need 46 resistors to cover all of the address lines? A level shifting IC would cost about the same, I think. And like lidnariq said, it would definitely be easier to route for a...

Thanks for the heads up, I may end up having to order from a fab in China. But I'd still be interested in recommendations of USA based fabricators, if anyone has one.

Hey everyone, hope everyone is doing well! I'm looking to avoid international shipping during the pandemic since it's slow and potentially unreliable. OSH Park is USA based, and is working as smoothly as ever, but only offers 0.8mm and 1.6mm thickness boards. Are there any board fabs that are in the...

I don't mean to thread hijack, but this is the exact question I was going to ask. If this isn't cool, please let me know and I will post a new thread. Warning: Hobbyist level knowledge here. I don't know much, and there's probably huge gaps in what I do know! Basically I plan to use a serial-in para...

Here's an aftermarket connector with little prongs for soldering: https://www.ebay.com/itm/173675679774 That's pretty expensive for just the connector, although I realize it includes international shipping cost. Try Console5... https://console5.com/store/parts/proprietary-av-plugs.html Another meth...

I have a donor SNES but I'd rather not stress the chips with hot air unless I have to. FWIW, you can use ChipQuik with a relatively low temperature. It really only effects the legs and pads without having to apply heat to the chip itself or the rest of the board. And even then, you can use a fairly...

Ah! Sorry, I'm not a morning person. My brain wasn't working yet. I understand now.

Thanks for the help!

RGB is neither NTSC nor PAL. As long as you run 60hz software then all should be fine. But I once modified a PAL SNES to output 60Hz and the colors were all messed up on my NTSC TV. I found out that it was outputting PAL60, and I had to modify the video encoder to output NTSC60. Won't I run into th...

So the NTSC (U/J) Gamecube does not output RGB. The PAL Gamecube does output RGB, but it's PAL. I've heard a number of people say on the Internet that you can use a PAL Gamecube in NTSC land to get RGB output for the Gameboy Player, but I'm confused about how to accomplish this. I can't seem to find...
