Super Everdrive vs. SD2SNES: What are the main differences?

What do you mean 98%, 99%, 100%? The point is you have to drawn the line, SOMEWHERE. The problem is someone out there is going to whine that shitty chinese pirate game X doesn't work. Or that some other obscure thing doesn't work. Many of your customers don't care about these games. It's not worth it to go out of your way to support it. Plus again, we are talking about *alot* of work to support a little bit more in many cases.

For example, Super FX is at most, 10 games. Star Fox 2 is the main one people want to play because it never made it to retail. The rest of the games are all affordable. Yoshi's Island may cost a bit more than the rest. To support these games you have to emulate a custom RISC CPU. You may have to spend months working on this. You may have to debug tons of issues. This is all mainly to support very cheap games, one unreleased game, and one moderate cost game. Meanwhile, there are other areas that could be worked on.

Let's look at a few others. SDD-1. This chip is less complex as it isn't a CPU. It does some bankswitching and graphics decompression. It could probably be supported fairly easily. However, it'll still take time to implement and the reward is Star Ocean and Street Fighter Alpha 2. Star Ocean is playable via the Game Doctor 96mbit hack already. So again, time management. Is it worth the time?

How about the biggest list of them all. SA-1. SA-1 is complex chip, even more so than the Super FX. It contains a 65816 cpu like the SNES, that runs faster. It has other features besides a complete cpu. It would take as long as or longer than supporting the Super FX. 20+ games use the SA-1. Among them are popular titles like:

Dragon Ball Z - Hyper Dimension
Jikkyou Oshaberi Parodius
Kirby Super Star
Kirby's Dreamland 3
Super Mario RPG

So we're looking at a few more games people may want to play, but much more of an investment in time to support them. You seem to believe that it's their lack of attention span that prevents us from having 100% compatible flash carts. But that's not it at all. Besides the time management (where is your time best spent) there is alot of huge engineering challenge to support these chips. I'm glad Krikzz and others didn't just stop everything to perfect one product. Especially since rarely if ever is anything perfect.

What is this about bunnyboy now and being made about the HDMI NES not being sold as a kit? Seems to be another subject entirely. Bunnyboy isn't privy to secret information you know. Other people have an idea of how to do exactly what he is doing with the HDMI NES. My understanding is it's possible to spy on the original PPU and with the information gathered you can reconstruct the output digitally and in whatever format you want, HDMI, RGB, Component, etc. There is atleast one other project out there aiming to make a replacement PPU.

 

I don't know if he is or not, I'm sure if he wanted it he would ask. He has made his source available though.



I don't think anyone knows Ikari's intentions here, to speculate why he would or would not create FX or SA-1 or any other is kind of presumptuous isn't it. I was under the impression that the SD2SNES was a project/hobby for him, assuming he would or would not create compatibility for something for the fact there is limited games or cheap common games makes it sound like he has made this for profit.

The SD2SNES is a brilliant piece of work, if Ikari never furthers the compatibility we already have at least we know it is capable of the task and maybe someone comes along and picks it up.

We can only speculate here on the forums though.

 

That is a good point. SD2SNES was created by him as a hobby. However I still think my point of time management can apply to some degree. But a lesser one. Since it is a hobby, I think people should actually be hopeful that he will finish FX support someday. But as with any hobby project, it's truly up to the hobbyist when and how much gets done. Short of throwing tons of cash and hiring him to do it. =)
