Fantastic News

cant wait to see the fruits of your labor

Hopefully the other great coders who visit willhelp too.

After this release is out the door, I plan to rewrite the graphics rendering code in assembler and possibly use the Dreamcast ARM sound CPU to emulate the SNES sound CPU.[/quote]
Its nice to see you got new energy to work on it. Thanks to keep Super Famicast alive, and best luck rewriting this ;D
I respect you for your perseverance.

The DreamSNES team tried in the past to use the ARM for the sound processing also, but it turned out that the ARM was to slow for that job. They where very dissapointed of the power of the ARM. Maybe I can find back a forum post about that.

It is good to see, how hard you are working on Super Famicast. But I now realise that the DreamSNES team has walked about the same paths. Because later on they also wrote the CPU core in ASM and it didn't work out. So I think they really did try to make it fullspeed instead of just adding options and making it more pretty.

Ofcourse I still hope you can overcome the speed problems where the DreamSNES gave up to.

No real Confirm dreamsnes gave up. It still will be very hard, to get speed close to dreamsnes let alone beat it. Â*With time and lots of hard work it's Do-able if you love the system, and have the passion. Just have to save every cycle you can. Use every optimizing trick you know. And get every one in the scene to help this really does help more eyes the better one person cant do every thing or know every trick.

Going alone does not work to well and takes more time to do every thing. there are times, when working alone makes more progress other times it' does not.

I say start a topic detailing, what needs Â*to be done to Snes9x and all of us can look at parts and try to get it faster or save a cycle or 2 Â*some were.

Im trying to get this happening with neogeo it has worked pretty well. But All of use have strong points and weak points.. combine together i think were pretty powerfull force .

Im Willing to help out and look it over any thing, i can do every now and then.

Support your passion for the project nice to see.

The ARM IS software overclockable, maybe that is the answer if it was literally too slow...

[Ian_micheal]

it's only 25mhz if i remember right i posted the real doc on it once. Every one stated 45mhz they wrote it to match that figger.

But in the real world if i remember the real doc it's 25mhz only But like you said software overclockable. If we had what the dreamsnes team did on it and re did the maths to suit the real speed of the chip we might get some were.

I dont know if they knew it was 25 mhz or not because on there forum they said 45mhz not that case.

[quzar]

it is 24mhz on its own, but is overclockable up to 99 (or 100?) but nobody knows if it can actually go up to that speed.

[scherzo]

Even 24mhz ain't that bad actually. If it's overclockable, even the better. It would be a very dedicated task which could be written in ARM assembler. There's much more people that know ARM than SH4 because of Gameboy Advance. If we could get someone like Loopy to help, that would be awesome. Of course, Loopy is plenty busy with his kickbutt project.

Does the ARM have its own memory like the PVR or does it use system memory? If it has its own memory then I'd worry about how much would data would have to be sent back and forth between that memory and the SH4 because then you'd have a similar slowdown when sending too much to video memory.

I know this might sound crazy, but maybe a whole new emulator could be written from scratch in assembler using snes9x as a guide. Im pretty sure that's what Loopy did with SNES Advance.

I'm all for teamwork. Yeah, at the beginning I wanted to work on it all myself, do everything I could by myself. Now I'm hitting roadblocks like DSNES did. Anyone is perfectly free to download the source and analyze it, screw around with it.

What would you all think about me opening a sourceforge project for Super Famicast? Then I could carefully which coders have CVS access and we could really make this a team effort.

If you look back at your old forum topics on the "fake" DC Emu, this was the route we thought you were going when you first mentioned the project

[scherzo]

Sorry I made you think that so soon in the game. I also recall saying that I wanted to see what I could do with it before officially colaborating with other coders. Not that I didn't welcome help. I just feel like Super Famicast is my baby. But the source has been there since day one. Yes, I recall you working on the netplay code and that's not forgotten, just on hold until later.

Why do you call DCEmu fake?
