A big thanks to everyone for their efforts and information! Sugam, I can't believe you're willing to do what you've written, you seem like an out-of-this-world philantropist. :D If the mobo CPU works and you send the thing to me AND I can't get it fixed, I'll definitely order a working one through y...

Well, I can't really test it with another CPU, but I probably can have the PCB traces fixed. In case that doesn't work out, I could send the PCB or chips to someone else who'd like to have a go at it.

Sugam, if the fine folks here manage to help you to repair the motherboard, please ignore my post. I'd definitely prefer to hear that you fixed it and didn't have to give it away.

Wow, what a great offer! Hm... I have a broken PAL NES and the most probable cause seems to be the PPU. Now, I'm guessing your NES is NTSC, so I believe that its PPU wouldn't really be useful to me for this purpose (I researched the differences on this forum and they really are big). On the other ha...

Hmm... Pilotwings worked just fine on my PowerPak (both with old and new mappers).

@MZ: Thanks for the clarification! @blargg: Great suggestion for the connector, thanks! I'll be sure to try it. Don't worry, I realize how good Yoshi is (and so does my girlfriend, it's her #1 game, so that's actually why I'm asking about it :)) - it's just difficult to get through if we can't save ...

Thanks, guys, I'm a bit smarter now. 8) I don't think I'll be getting Retrode any time soon, the coolness factor of it aside. It's too expensive for what I need. 75€ with the shipping. The Mash Mods programmer is much cheaper ($62.50 with shipping). That I might think about. Any ideas on whether it'...

Oomph... Seems I'm in over my head. :D Dwedit, no way would I be able to do something like that, I'm afraid. The Mash Mods programmer does say (in the manual) that you can write backed up saves to all cartridges. That should work with this one too, right? I don't see why the SuperFX would interfere ...

My first post in quite some time now... I need to find some time for SNESdev. I bought Yoshi's Island for my girlfriend, on eBay. We played it for a couple of months on/off, when suddenly a strange thing happened. The image on the TV was "zapped", as if a tiny burst of current distorted th...

Thanks for the tips, guys!

I'm sure I'll have many questions when I learn some more.

Have you checked to see if your homebrew rom image has the official "Nintendo" information near where the interrupt vectors are? As in, the information about the Internal Name, checksum, mapper (mode 20, 21, etc), ROM size (power of 2), Battery RAM size, version, etc. Your post made me re...

I tried expanding xmsnes.smc and magenta.smc with Lunar Expand and UCON64, along with trying both the .smc and .gd3 (thus, 4 possibilities). Nothing worked better than before, same problems. I was a bit taken aback by the fact that the .smc and .gd3 had 524800 bytes instead of 524288, but I understa...

Ahhh, finally some progress. :) Expanding to 4Mbit with Lunar Expand (a Windows tool :(... is there a way to do it with ucon64?) partially worked. The colours/graphics are very messed up. XMSNES loads with a very light background color, the graphics are mostly invisible and the font is barely readab...

Great stuff, Memblers, thanks. I'll try and take a similar path to knowledge. Unfortunately, fixing the checksum (ucon -chk) along with converting to gd3 (-gd3) or rewriting the smc header (-smc), even combining the checksum fix and header repair, didn't work with the PowerPak. I'd really, really lo...

First of all, I'd like to state that I'm a complete n00b in SNESDev. Regardless, it's not my code I can't get to run on the PowerPak, it's someone else's. I tried some tutorials here and there, read up a bit on the 65816 and then realized something - I should first try to get any kind of example cod...
