Gpx2 Unvailed!!

What I want to know, is why does this thread not stay on the top?

Edit: Ah, news.

​

Because it's in the news forum. If the topics in this forum move to the top when there are new posts, people can get confused and think that it's a new news item.

 

[rabbits with hats]

This should be pinned

 

[Esn]

games with huuuge hand drawn backgrounds?

​

Yay! Perhaps I should try something...

​

Actually, more often than not these long threads get updated with more news about the subject (ex. the Wanna Be Wizard translation thread and the Lynx emu thread) and because they do not stay near the top a lot of people don't notice the updates. If I had my way the News section would be like all other sections (but I don't, so it's not ).

Who Are Making These!

​

Well gpx2.co.uk belongs to Craigix, and gpx2.org belongs to Mike Dawson (gpfrodo, gplink). All it takes is a simple whois lookup, or in this case a bit of common sense (gpx2.co.uk is linked from gbax.com and gpx2.org is full of Mike's software).

​

nice to hear that the author of gpfrodo is intrested in the GPX2, so i dont have to miss that emu

It will likely be a problem getting Neo Geo to run full speed, but it is better than what we have now.

​

I had a fully 100% speed Neo Geo emulator on a 166mHz PC running under windows 95 (with only 2MB video card iirc) so why can't it be done on GPx2?

I hope someone can get it running Amiga at a respectable speed. Then I'll be completely sold. GBA and Sega CD would be nice if possible too.

As for craigix's video.... I might have to put that on my GP32 when it's released B)

In other ramblings......

with a portable you could be on a train or in a car and every bump will travel right through you to the controls making it a frustrating affair.

​

How does the PSP cope then?

If I had my way the News section would be like all other sections (but I don't, so it's not ).

​

You can configure it to be that way yourself you know. Sure you have tod do it every time you caome in, but it's better than nothing.

Well for one by not making too many games that you have to play with the analog, secondly it's VERY tight, close to the surface... well most specifically it's not a stick, more of an analog "nub" so it takes a more deliberate push to move it.

That said I still use the Dpad for Ridgeracer, it's just easier.

Full speed WITH full sound on a 166 MHz PC without massive frameskip? I find that very hard to believe.

 

[Jaw]

yeah, easy. just get a shitty optimised emulator, like neorage, sacrifice most quality, but good speeds

Well believe it, because I also had a 166Mhz PC running NeoRage fullspeed w/sound.

Well I find that interesting that you mentioned Neorage Jaw, because that was the emulator I was using, NeoRageX. It appeared to be very highly optimised, as I made sure there was no frameskip and the sound was set to 22050Hz 16bit, and everything ran smoothly. It didn't even matter if the emu didn't have the name of the game that you wanted to run supported, as it could run any true Neo Geo rom (not those butchered ones that mame uses) without any problems, the name would appear in the menu. It could also run the games if you didn't have enough ram, by buffering it onto the HDD.

Sure, the GPx2 won't have that ability (HDD), but if a low end PC could get such a highly optimised emulator, then I don't see why the same couldn't be done on the GPx2 with the right talent. Especially if Craigix's assurances that the power will be much better than what the specs quote is true.

 

[x68000]

if the pc can run neo at that speed with a bulky OS weighing it down, then we should hopefully get a stunning neo emu on the gpx2 with some competent programming.

 

[junker]

yeah, i remember running games on NeoRageX on the old, weak computers back in high school at full speed. those were the days..

​

I had a crappy old P90 laptop with 16MB RAM back then, and ran NRX on it. I had to turn sound off, and frameskip it down to 15-20 fps to get "full speed."

I suspect the 166Mhz people had to use some degree of frame skip but just didn't realize it because it wasn't too bad. Maybe not. I do know my 300Mhz P2 PC ran it very easily at 0 frameskip full speed with sound, so... Would be nice to hear from someone who used a 200Mhz PC.

Anyway, I do think a full speed NeoGeo emu is possible on GPX2, but we may need to use some frame skipping to keep a consistent speed. Then again, if the co-processor can be used to offload some of the video/audio processing (similar to how emus use the GBA hardware sprites and tile engine, and how YoyoFr is using the PSP's media engine for SNES) then full speed NeoGeo with sound at 0 or 1 frameskips might be well within reason.

Also, since we already have Reesy's tweaked Cyclone from DrMD, a NeoGeo emu could already be pretty fast from the start. That's one nice thing about GPX2 compared to PSP - there are already several optimized ASM emulator cores for ARM.

At least we do know full speed Genesis at 0 frameskip should be a definite.

Comparing a Pentium to an ARM is not a real good comparison though. A pentium is a CISC where as the ARM is a RISC. A pentium is more powerful than an ARM MHz for MHZ. So a 200 MHZ pentium may be like a 400 MHz ARM.

The PSP needs 333 MHz to make those emus run well. The GPx2 is only 200 so to make up the speed difference the GPx2 versions will have to be written in ASM. MD is likely *if* Reesy gets the GPx2. SNES? well all of the SNES 9x team has gone to the PSP so not sure who will do a GPx2 version.

Neo geo may be doable if the second CPU can be used. Cyclone is pretty good but there are still a few bugs left in it. Not sure how that will effect Neo emulation.

 

[Prophet]

OK, you're right on those accounts Dave.

I'm just trying to be positive.

Funny in a way - you are always the eternal pessimist, and I tend to come from the other direction, but in the end we usually meet up with same overall conclusion - i.e. the Zodiac controls did suck afterall.

I just hope the GPX2 _is_ better than the specs sound, as Craigix suggested.

I have one pre-ordered now anyway. I like portables, I like Gamepark, the GPX2 looks like my favorite system design ever (NGPC) and at the least we have Reesy and DrMD.

Wonder if YoyoFr is interested in it? I'll try to find out...

 

[Prophet]

Here's a good question - how fast do the NeoGeo emus run on Dreamcast? I never used emus on my DC, only official games. But I know there are tons of emus for DC.

DC was also clocked at 200MHz, and I believe the SH4 is also 32bit RISC.

Seems like Dreamcast might be a decent way to gauge what emus on GPX2 *might* be like.

 

[Sonic-NKT]

snes is perfect without sound, but there was no work on this emu for several years.
NeogeoCD, with optimized cores runs fullspeed, sometimes slowdowns
Megadrive, not fullspeed with sound, missing a highspeed core the gp32 has
Amiga 500, not fullspeed yet, but chui is workingon it
Mame, bigger compatibility and faster than gp32 mame
GBA, Sloooww
PSX, homebrew, slow
PSX, Bleemcast, fullspeed
then it has all emus the gp32 has below the specs of those systems.

but remember the dreamast has less ram and not a second core (which could be programmable)

Hum, I was under the impression that RISC was more powerfull. Reduced instructions or something, opposed to complex instructions...

RISC is meant to allow for more instructions per cycle than for CISC but they're much simpler instructions. If you don't use fixed point maths, the speed goes way way down.
