Re: 4k tvs and classic systems...

It's sad really how eventually every CRT will be broken with no way to fix it. Kind of like the CD-I and it's poor design choice to put the battery inside of the RAM chip. Thank god we have emulators. This is no different than any other item mankind has ever made. CRTs can last a very long time. Th...

Re: NES cartridge maximum current

If you only intend to use it on your own NES you could upgrade the power delivery. Or your could design the cartridge like the SNES copiers and have its own power supply to the cartridge.

Re: Can't see Mario - Bad NES?

I guess a dirty connection wouldn't make sense for a clean no sprites appearing effect. More games tested and pictures would help with diagnosis. It could just be when they replaced the connector they damaged something or static electricity zapped the PPU. It would be a pretty weird failure to have ...

Re: Can't see Mario - Bad NES?

The issue sounds like no sprites are being shown and only the background layer. There could be multiple potential causes for this. First you should clean the game cartridges if you can. Just because the connector has been replaced doesn't mean you don't have to clean the cartridges. If you have the ...

Re: 4k tvs and classic systems...

You need a good upscaler. The XRGB Mini/Framemeister is a popular one. Yes it will cost you between $400 and $500 probably but it's a scaler designed for these older systems. Newer TVs mostly don't bother with any analog video connections anymore because all the modern devices pretty much use HDMI n...

Re: How to put in cartridge without losing save?

I wonder if people pulling out cartridges with the SNES still on is why it seems like you can find a lot of dead SNES systems. I remember reading it was some fuse that tended to pop on the SNES so I guess the two might be related.

Re: Using Roger Clemens 53361-2 (MC-ACC) as an MMC3 donor?

I don't think it's missing an address line because the game you mentioned uses a 2 megabit CHR-ROM. I cannot tell you the pinout of the MaskROMs or the MC-ACC chip but it is apparently a MMC-3 clone. If they are compatible with standard EPROMs and you have sockets on the board, see if the original M...

Re: How to put in cartridge without losing save?

You should hold reset while powering off the system. You should also be sure your cartridges are clean. You may also need to clean the connector in the system.

So you're saying this eliminates the slowdown?

Re: Found cause of slowdown in Empire Strikes Back

Care to share what routine you patched out that eliminates slowdown? So others can try it out? I've played the game recently and am aware of the slowdown problems.

Re: Why did Super Mario RPG and Kirby Super Star use an SA-1

Did SNES carts typically have more data in them than PCE carts? Off topic, but does writing slow code really save time? What if code becomes so sloppy that it slows down development, and the only way to clean it up is by optimizing it? Because the SNES only used cartridges and outlasted the PC-Engi...

Re: Found cause of slowdown in Empire Strikes Back

Which slow down are you talking about? Just general slow down when there are a lot of objects on screen at once or something more specific?

Re: Why did Super Mario RPG and Kirby Super Star use an SA-1

But what about comparing the SNES to the TurboGrafx 16/PCE which does share CPU design? And its CPU really does run at over 7mhz. And it came out prior to the SFC. But it doesn't share the same CPU design. The HuC6280 is 8-bit. It's a slightly souped-up NES CPU. All that demonstrates is that Ninten...

Re: Why did Super Mario RPG and Kirby Super Star use an SA-1

I don't understand why you say sloppy programming like they should have just "got good" instead. In the real world of making these games the consumer and the developer doesn't care if a game has sloppy code. The consumer cares that the game works and the developer cares that the product is finished...

Re: Why did Super Mario RPG and Kirby Super Star use an SA-1

To be exactly how it is, it might require the SA-1. But I think the idea is that the same general game could have existed without the SA-1. It's harder to tell versus something like the Super FX games that clearly required the added hardware. I think the SA-1 is a nice idea, maybe even worthy of bei...
