Re: Is this Battletoads?

But then the Street Fighter II game engines extend vblank to fit bigger copies to VRAM. I can see the letterboxing even on an NTSC Super NES and a crappy TV. Such games would have more reason to crash if the vblank isn't the expected length. It dosen't crash, it give you the "region lockout&qu...

There are two lockouts: the CIC lockout and the PPU lockout. Like the NES, the Super NES has different PPUs in different revisions: one that generates 262 lines with NTSC color and one that generates 312 lines with PAL color. The game probably detects your PAL PPU. I think the 50/60Hz switch mod wo...

I use a Mega Drive wall wart on my SF7 and it works fine so you shouldn't have any problems if you can find one (I use 2 x 64MBit modules in my SF7). Also, if you plan on using your SF7 regulary then it might be a decent idea to look into getting or building a CD-ROM unit for it. The required CD Dri...

We had a similar style of spamming over on the Minimig forums. After discovering that all the spam was coming from a particular IP range then it was a simple matter to block access from that IP range. Had the side affect of blocking a (probably) large number of users form a particular ISP in a parti...

Anybody have any idea what kind of emulator bug is being exploited? Isn't it possible that in the future newer emulators will also have problems running SMA?

. What exactly do you mean? Can't the CPU just enter a RAM loop? Yes, but there is "only" 128k WRAM available. Not fun to sacrifice half of it for your program loop. With the SA-1, both your CPU program and SA-1 program can execute right off the game pack ROM. The SA-1 memory controller w...

I wasn't aware that most of the extra pins are unconnected. My comment was due to the fact that if I connect star fox to a game genie, which does not pass through the extra connectors, it does not render any SuperFX generated graphics. Maybe it's not so much the extra pins as it is the extra ground...

There are SuperFX games that use the 21mhz mode. Also one of the "extra" pins I believe carries a clock signal. But I think that most but not all Super FX games have their own clock in the cartridge. That's true, but I have only every seen that pin unused in the 'glop top' SFX carts and t...

Judging by the prototype board it doesn't look like it will support SuperFX. The prototype is missing the extra cartridge pings on the edges that you find on cartridges with add on chips. I hope it changes in the final version. I'd love a powerpak like cart for SuperNES. Especially if it will play ...

Hojo, that would be totally awesome, but I won't get my hopes up on anyone completing such a project. I'll believe it when I can buy it. ;) I regularly visit the guy's (Scott Goldman) blog. He seems to be making a decent amount of progress and if I remember correctly he's doing it for some academic...

Now I'm just waiting for the first flash cart with a SuperFX :wink: Your prayers might be answered: http://sneshack.blogspot.com/ It's a cart in the same vain as the Powerpak. It uses a SD card to store the rom images, ram and a FPGA to make it all work. I dare say that somebody with enough know-ho...

Hmm. I don't get why that schematic is using a bus transceiver. I thought for a few minuets and came up with this: (sorry for the crude MSPaint) http://www.jcomcp.plus.com/16to8bit.PNG This circuit replaces the transceivers in the design you are using with 3 state transparent octal latches (74xx373)...

The model number is more important than the description. The seller must be thinking "It looks like it has 40 pins so it MUST be an IDE drive". There was a ton of information on this on the old Cherryroms board which has long since died (did anybody archive it? There was some good stuff th...

I could get away by only shifting the tileset, but without using fine-scroll for that so that it simplifies things. Or I could just turn the screen to black and fade it in with the new screen, without any scrolling. It wouldn't look as good but the gameplay wouldn't be affected in any way. Perhaps ...
