Hows Opensnes9x V0.3 Comin On?


Probably quite well, I'm sure yoyo is preparing it well for the GBAX2004 competition thingy.
 
i hope that the gba emu and psx emu coders both know bout this
we would have one very nive day!
hmmm..... snes....gba....psx on my gp32 that should get here soon...
I already contacted the guy makin the racing game and maketupon or whatever his name is bout the coding comp, and i talked to the guy who was doing the fft remake bout it..

Hardware Specifications

Thus dids't the Playstation come forth from the dark alleys of Tokyo... This is one serious gaming machine. SNES, Megadrive, 32X, Jaguar and 3DO all pale besides this monster. The PSX has 5 processors running concurrently, similar to the Atari Jaguar. Then main processor is the powerful LSI R3000A 32 bit RISC processor (licensed from SGI), running at 33.8 Mhz. In addition to it, there is a 66 MIPS High-speed Matrix Processor for calculating 3D polygons, there is a graphics processor for displaying sprites (2D) at 60 frames a second, a sound processor for doing CD quality sound and a 80 MIPS Data Expansion Engine for decompressing graphics and sound data from the CD-ROM.

What does it all mean? Well, this machine is built for 3D! And since that is where the games are going, we're all set. (In all fairness it should be mentioned that the Sega Saturn is on par with, if not better than, the PSX on 2D scrolling games, note 2D only. However, this is not a problem since these machines are lightyears ahead of the competition anyways!)

CPU

R3000A 32bit RISC chip @ 33.8mhz - Manufactured by LSI Logic Corp.
Clearing capacity: 30 MIPS
Bus bandwidth: 132 Mb/sec

As stated above, a very kuel CPU, slamming the 68000 in the Jaguar and the ARM 60 in the 3DO, even the Hitachis in the Saturn! A high bus bandwith is important when using lots of colors in fast moving animations! (Like Tohshinden)

3D Geometry Engine

High speed matrix calculator
Clearing capacity: 66 MIPS
1.5 million flat-shaded polygons/sec
500,000 texture-mapped and light-sourced polygons/sec

Ahhh, the key to the ultimate 3D performance. Note, however that the above specs are rather optimistic. There is a slight difference between displaying random polygons on screen and calculating whether or not a polygon will be visible or not as the arm is lifted in defense, then shown according to the position it is in. Toshinden achieves 80.000 of the latter polygons, a very impressive number for such an early game. Expect this to increase as the programmers really get to know the hardware. Luckily the Playstation development setup is hailed as being among the best in the industry.

Data Engine (MDEC)

Clearing capacity: 80 MIPS
CPU, direct bus connection
Also compatible with JPEG, H.261 files

A very important player. It even helps cutting down load time, since the data can be loaded from the CD in compressed form, then uncompressed on the fly by this baby! Note the support for industry formats, not just proprietary.

Sound

ADPCM, 24 channels
Sampling frequency: 44.1 Khz

CD quality sound! What more could you ask for... Well, since you ask, it would have been nice if it had a little bit better sound support. By all means, it is great for using sound of the CD, but more or less incapable of producing sound on its own. Oh well, you won't notice it!

Graphics

16.7 million colors
Resolution: 256x224 - 740x480
Sprite/BG drawing
Adjustable frame buffer
No line restriction
Unlimited CLUTs (Color Look-Up Tables)
4,000 8x8 pixel sprites with individual scaling and rotation
Simultaneous backgrounds (Parallax scrolling)
360,000 polygons/sec

Why do people question these specs? OK, so the Saturn might be a bit better on 2D, but read the specs again. Parodius has some slowdown, NOT because of lacking hardware, but due to programmers not used to the system. Raiden has less slowdown, i.e. more experienced programmers. So in 6-9 months we should see no more slowdowns in 2D scrolling games. Relax, the hardware CAN handle it!

Memory

Main RAM: 2 Megabytes
VRAM: 1 Megabyte
Sound RAM: 512 K
CD-ROM buffer: 32K
Operating System ROM: 512K
RAM cards for data save: 128K EEprom

Hey, it's more RAM than many other consoles out there! Stuff can be stored in RAM in compressed form, then uncompressed on the fly during gameplay. So don't expect that this will limit its performance. (You just can't compare how much RAM the PSX has vs. a PC. It is a totally different concept!)

CD-ROM

Double speed
XA compliant

It's faster than most other CD systems out there! And they sometimes even let you play games while you are waiting. (We're talking 6-7 seconds.....)

I think the idea is that the PSX emu could possibly run small low impact 2d games like Gunner's Hevan or things from demo disks, I doubt anyone expecting to play Tekken with it.
 
tekken : no, of course...
but FF7....and gran turismo 2....they will rocks :lol:
no kidding : even ridge racer would rock...even the 1st demo disk would be cool
we will have to wait till the release :)

see you :lol:
 
You won't be able to play FF7 on it for certain as even with movies stripped from the game it still is over 128mb
 
Wil it be able to play Tombi. mi friend had a demo disc of it once and me played it for hours!
 
As optimistic as I'd like to be about actual PSX games there are just some things that would be too much of a headache to try and play on a GP32 and FF7 is one of them. even if it were split between 3 SMCs and had FMVs stripped (which frankly would make the game worthless ans half the story is in the FMV) someone would still have to do all the stripping and then who will anyone get it? It's not s if we can advertise a stripped version on the forum, the mods would pull that down with the swiftness.

Roms may be easy to find, but hacked PSone game images? I'd hate to think about would google would spit out for that.
 
you could upload the ISO from your PSX discs and strip them yourself... It wouldn't even be illegal to have on your SMC's, unlike downloaded ROMS
 
Maybe we could put the story for FF7 into the VNS :rolleyes:

Or how about converting it to GPcinema ;)

Seriously tho even I think FF7 is a bit of a tall order :)
