I may be just adding an unwarranted spin on the opinions of better-informed folks, but personally I consider the discrete 2/1/3 to be the standard "real" SNES - the 1/1/1 is buggy, the 1CHIP and Jr. have subtle PPU differences (byuu has described the Jr. as a clone console), and other revisions are super rare.

On the other hand, apparently the 1CHIP and Jr. have crisper video output...

Unless there's a reliability issue I'm unaware of, the rev.1 CPU is only a problem for SNES development as a whole, in the sense that every game has to avoid carelessly mixing DMA and HDMA because somebody out there might have a rev.1. Unless there's a game somewhere that actually triggers the bug, owning a 1/1/1 can only be a plus, as testing your own homebrew on it could alert you to the fact that you've triggered the bug. If you don't write homebrew, I'm not sure it matters.

I have my Super NES since 199X. It had a problem with the board (PPU burnt due to the power ac). Other than that, it's working up to the present day like a charm.

Are you saying the SHVC-CPU-01 1/1/1 is a bad version to have since you said 1/1/1 is buggy.
I have a 1/1/1 and it works fine. I never use homebrews at all. I do have a SHVC-CPU-01 2/1/3 by the way as well. Is the SHVC-CPU-01 really a bad version to have, because i grew up with a 1/1/1 and it never failed me for the last 10 years.

I'm just referring to the DMA/HDMA clash bug. I'm not aware of anything else, and I don't know why they revised the S-PPU2 twice. What I mean is that the 2/1/3 is what the 1/1/1 was supposed to be before they realized it wasn't and changed it. For someone who just uses it to play commercial games, there is no practical difference as far as I'm aware; games are simply written to not trigger the bug. (There is indeed one football game (I think) that checks the CPU version and uses block move instead of DMA if it's rev.1, but it turns out block move is fast enough to work fine in that case so it's not clear why they bothered with the split.)

I'm not an expert on the detailed revision history. But it appears you've already been through that to some degree on AtariAge...

I said write homebrew. It's the programmer's job to avoid the lockup bug. If you're not a programmer, don't worry about it.

...

...wait. How accurate is the TCT-978? I know I said that it wouldn't be worth it to do a production run of 5A22 chips, but it seems somebody in China disagreed...

Aren't there adapters to get around the difference in cartridge shape between JP and US releases?


Any import adapter, or Game Genie/Action Replay/GameShark should do.

least helpful post in thread incoming:

In the long term, the most cost-effective long term solution will be emulation for any old computer worth preserving.

In the past, I didn't want to accept this reality.

Now I'm increasingly comfortable with it and agree with Zep, creator of Pico-8 that what matters about a console is not the hardware but everything else.
