Re: SNES PPU Problem

Unfortunately I'd already looked at his logs before posting here. None of his cases seem to match mine. My console isn't failing any electronics test, it's just the graphical problem.

Re: SNES PPU Problem

Using a scaler and a LCD I was able to take much better pictures. Unfortunately I don't have a capture device but this should illustrate the problem.

SNES PPU Problem

My SNES that I've had since it was new has developed a problem suddenly. Sprite graphics have vertical lines through them. I'll attach an image to this post of Mega Man X to demo the exact fault. I'll try to get a clearer picture later. Sprites end up with vertical lines through them near the right ...

Re: Introducing the VeriSNES (FPGA-based SNES)

Since apparently SNES consoles are known to have CPU failures, have you considered using your work to use a FPGA as a CPU replacement? I wrote the code with that idea in mind. The pinouts on my chips are identical to that of the original system. The primary issue to consider would be voltage level ...

Re: Introducing the VeriSNES (FPGA-based SNES)

Since apparently SNES consoles are known to have CPU failures, have you considered using your work to use a FPGA as a CPU replacement? Obviously a whole system replacement is great too, but I was just curious if you think a CPU replacement working with the rest of the original hardware is a possibil...

Re: Some carts work fine, some with glitched graphics, some

Some cartridges do draw more power and that can always cause weird problems when you are on the edge. I actually had a 3rd party SNES Power Adapter I used for years and never noticed any issue until using InfiniteNESLives' SNES flash boards. Games would randomly reset/black out. After getting an off...

Re: Some carts work fine, some with glitched graphics, some

Pictures of the glitched graphics can sometimes suggest a particular signal problem. I've never heard of using toilet paper. I usually use a pencil eraser and paper towels with alcohol. The list of games you have makes me think it's a problem with the cartridges. I say that because I don't really se...

Don't destroy old carts, even text heavy Japanese ones.

Re: Some guy made a modloader inside an unmodified SMW cartr

My favorite part about this is that you can get a smw cart to dump itself to the screen with some convoluted controller inputs. With Nintendo's view that coping devices are illegal , logically they would consider the TV, SNES, controllers, multitaps, SMW cart itself, and the keyboard-PC-hexeditor "...

Re: Some guy made a modloader inside an unmodified SMW cartr

Tangent question: Is there any risk at all hotswapping carts in a NES? I've done it hundreds of times. I don't think the risk is zero but it in my view it's pretty low. I thought I read somewhere that one thing that enables or helps with hot swapping is by having the power connection pins longer th...

Re: Request for new mappers

With out the DMA/BA pin on your 6502, doing a Super CPU in the cart is going to be tricky, you can keep a CPU in it, but how are you going to get data where the NES CPU can see it? I guess you could send an IRQ to the NES CPU, it then writes to say it got the IRQ, then you bank a chunk of RAM into ...

Re: Some guy made a modloader inside an unmodified SMW cartr

With the number of SNESes that seem to be suffering sudden CPU/PPU failure in recent years, encouraging a cartridge hot-swapping fad seems like the height of irresponsibility... I agree. It seems like a bad idea to me. But I don't think too many people will be trying to copy from one SMW cart to an...

Re: Request for new mappers

I'd like 4kb bankswitching granularity, for 4+4+4+4 and 16kb fixed. Also, a hardware zlib decompressor chip. How about a second 6502 type CPU at 20mhz with shared RAM to communicate with the NES CPU giving you all the computing power you could want. The NES CPU would just be the middle man between ...

Re: Some guy made a modloader inside an unmodified SMW cartr

He mentions a method to copy data from one cartridge to another by hot swapping cartridges. I thought I read somewhere that removing cartridges from a SNES while powered on is a good way to blow a fuse. It's a cool creation though, a step up from flappy bird. The telekinesis mod looks to be entertai...
