yeah, I'm just expressing my full thought on the matter as well, not trying to bug/annoy you or anything...
I agree SA-1 would be awesome, but until I see it on Work In Progress list I don't get my hopes up. I don't believe Ikari_01 has ever promised SA-1 support, until he does its not on my radar. I do hope to see it one day though.
Lol no worries, I thought you were saying I want cosmetic changes before SA-1 support. Trust me SA-1 would be huge, but like I said in previous post until he says its going to happen I am not getting my hopes up.
true , ikari_01 hasn't said yet for sure if SA-1 is possible or not, but a man can dream and hope.... :sneakiness:
got today my email with the information that he finishes my cartridge in the next days <3 i'm so hyped! B2T: SuperFX > SA1 > GameGenie > everything else
I could swear that early this year SA-1 was on the "to do" list, while S-DD1 was on "to be determined", while now the reverse is the case. Even at the time, I thought that was funny though. So yeah, we'll see. *fingers crossed*
I mainly keep my hopes up because the sd2snes has a Spartan fpga that is quite powerful as we see it in other projects... though the SA-1 could be a complex thing and have other problems... we'll just wait and see what happens :triumphant:
I've heard things about SA-1 being a fairly powerful, complicated chip, and then there is the matter of the game code going to the SA-1 first, which is true for the S-DD1 as well, but the S-DD1 is, I gather, far less powerful. Oh, and there are the weird copy protection things that SA-1 has that I don't think any other chip has (including S-DD1). SA-1 games are the least likely to play nice with clones, and I think I've even heard that, for example, Super Famicom Mario RPG won't run on a U.S. SNES. If I had my U.S. SNES, I would test this myself, but it's at my dad's. I don't know that much about this stuff, but it sure seems tough.
Yep, that's more or less what I know too for the SA-1 Eyedunno... all that "internal protection and CIC" schemes are the "other problems" I am referring to in my previous post. I am certain that in the end ikari_01 will make his best to either implement it or try to implement it, if he succeeds it would be pure awesomeness, if not there will certainly be no complains there :love-struck:
Is it possible? I haven't heard of a memory location games could ping to reliably if at all identify SNES (or N64 for that matter) between US/JP/Korea.
Lum, SA-1 and SDD-1 contain CIC functionality inside them. However you are correct that US and JP consoles are the same region and you cannot detect any difference between them. The issue with playing those special chip games is for NTSC versus PAL only. Eyedunno, SA-1 contains a full 65816 CPU that runs faster than the one inside the SNES. It also contains other features but the top thing to keep in mind is that it contains a CPU. SDD-1 however contains no such CPU. The SDD-1 primarily provides graphics decompression which is now fairly well understood. It also contains some memory mapping features. Compared to the SA-1, the SDD-1 is hardly a challenge. The SA-1 is probably the most complex add-on chip for the SNES (used in the US). After that perhaps the Super FX followed by Cx4. I'm not sure how complex some of the chips used in Japan or lesser known games are. The point is the SA-1 should probably be equal to (atleast) or greater than the amount of effort involved to simulate the Super FX.
IIRC the ST11 is another cpu and the ST18 is an ARM cpu, both are used to calculate AI or something in two games, one for each... I believe that the ST18 is the most powerfull chip of all.
Um, you mean just normal saves, like in RPGs or Super Mario World? You should be able to save normally in-game, and about half a second after you do it, the write LED will light up and it will save it to SD. There are a few games that near-real-time saves don't work on (I haven't encountered one yet though), and in that case, you have to press and hold the reset button until the LEDs light up. If you mean savestates, you can't do that, and as of right now, there are no plans to implement them, at least going by http://sd2snes.de/blog/status.
@MottZilla yeah these 2 games that use the ST11/18 cpus are some Japanese strategy ones if I understood correctly, luckily they are not that "important" to bother with them IMHO
