Just curious, do we have a database of games that use color emphasis? I've just never known if I am seeing it or not on a game; I don't think I've seen it enough to really know, aside from a time when screwing around with bare fingers on the famicom PCB caused the blue emphasis to kick in for Super...

So far it's run everything I've tried without problems.

*bump* Came across another game that needs this treatment. The megaman 4 minus infinity romhack the brightman stage (lightbulb dude) has colour emphasis on every part of the screen except a horizontal bar where megaman is. I'm looking to disable that if possible. In the debugger the code I think is ...

Ok, so it looks like Stunt Race FX grounds /CE, StarFox (the QFP chip version, at least) and Yoshi's Island do not. They all ground /OE though. I'll have to test my flash ROMs and see if they work with /OE grounded. It does, unfortunately, mean that I won't be able to reprogram them on-cart. Oh wel...

Another tangentially related question. I've read a couple of places (including that FAQ) that the ROM CE and OE are both grounded. WTF? How does that even work? Aren't addresses latched at the falling edge of CE or OE, whichever comes last? So then how is it possible that both are grounded? They're...

I discovered that the original nes / famicom control pad pcb the controller stops working once you make the cords longer than a certain length. In the dogbone controller pcb they fixed this, here's the fix: http://i.imgur.com/Jvt1vAE.jpg 3.6k ohm between vcc and cup 3.6k ohm between out 0 and vcc An...

What are you doing for input? Why is the crystal (filter?) floating in space? Any thoughts about a more permanent design? I'm going to straight wire the controller into a svga port. The floating crystal is because when I first wired it up I got heavy jailbars, I thought maybe the crystal was adding...

After seeing some cool consolized gamegear projects I decided to tackle a consolized gameboy advance. I used the gba tv converter for this project: http://i.imgur.com/XQntG01.jpg This converter is the most common tv adapter for the gba (it's also very cheap). And the best news is bacteria was nice e...

That's a whole bunch of nothing to look at...I checked out your channel though. That mario world romhack looks really well made and fun!

I like the back of your cart in the original post. It's like someone who's had an operation and has a tube port in their skin somewhere. Haha thanks. Matrix style? The goal is just something where you can easily change all the parts except for the ram chip. Wasn't aiming for the cleanest look, just...

Don't do the resonator thing it's dumb. Just disconnect the superfx clock trace from everything and wire up a 4 pin oscillator straight to it. If you ever want original speed just wire it into pin 1 of the cartridge connector. Since different superfx games overclock to different speeds I just make s...

It runs 4, 8, 16 mbit eproms, has a battery circuit, has 512k of ram wired up, has all necessary connections on a header at the back for overclocking.

Apparently some copies of mario world 2 came with a different version of the gsu2 superfx chip called the gsu-2-sp1:



I'm wondering if there's any known difference between this chip and the regular gsu 2.
