[BOUNTY] Injecting PSX Images into Native PSX Emulator - $280+

---

** I haven't been around to keep this thread updated. Thankfully, AriStar has done a great job maintaining an extension of this thread over on the developers board. For the most updated status, please follow this link: http://forum.xda-developers.com/show....php?t=1097428 **


I'm looking start up a bounty to get a development effort going around the Native PSX Emulator that comes on the Xperia PLAY.

The preloaded Crash Bandicoot as well as the selection of PSX games available from Sony use this native emulator, the performance in which is PERFECT, compared to FPse and PSX4Droid which have sound and choppiness issues at times.

Some discussion on this topic is in another thread, here: http://forum.xda-developers.com/show....php?t=1044755 . We can see the psx image on the SD card with little effort, however the formatting of this image and the steps required to inject our own images is still unknown.

My ultimate goal here is to be able to run FF7 in the Native PSX emulator and support the disc changes needed. (From the PSX Emulator menus, disc swapping looks to be included, but as no multi-disc games are released, this may be tricky).

I'd like to throw in $20 to start this bounty and get discussion going.


Please post under this thread if you can contribute either to the bounty or to the development effort. If you have any requirements attached to your bounty contribution (ie: "Must be able to play FF7") then please include those as well.


Bounty now up to (or over): $280 + Xperia X1

Disc swapping is probably less of an issue than it sounds - you only have to swap discs once every 10-12 hours for most games, and almost every single game that has a disc swap also lets you save after completing the disc and before the swap, so in theory if the PSX Emulator only allows for once disc at a time, you just make a wrapped image of each disc, save when you hit the end of one disc, and boot the image for the second/third/etc disc and voila.

While ultimately it would be a great feature, it's probably not strictly necessary and will amount to a minor nuisance in the short term.

Also, put me down for $10CDN towards the bounty as well.

10 Euro more. As long as it works, I'm cool with it.

Nice idea.

But my games run perfect in fpse.

Tell me what games you find choppy and i'll test them for you. So far i've played -

Time Crisis (touch screen as light gun, dam awesome)
Demolition Derby
Rampage Universal Tour
Point Blank (touch screen as light gun, dam awesome)
Strider 2
Die Hard Trilogy

and they all run flawlessly.


Would of tried more but i've been hooked on the nes/snes/master system/genesis and native xperia play games (backstab/nova2 etc) for the last month.

The one I care most about is Final Fantasy 7. Battle sequences tend to be choppy, the sound slows to a crawl when coming into and out of battle. The music sound sync in general also just isn't perfect. It's "good enough" for the most part, but stammers a bit, feels like a beginner drummer that can't really keep time.

Yeah sound emulation is more difficult to do than it seems. A ton of emulators (even today's Gamecube/Wii emulator, or the PS2 one) have sound issues more than anything else.


Also, I'll throw in $20 CAD for this. Hopefully it's actually possible and Sony's emulator is actually already complete. It'd be a shame to crack it but only find out it needs to be patched by Sony anyway.

final fantasy VII runs pefect to me on fpse, did you turn the sound sync and boost mode on?

Yeah ive turned on sound sync. It helps but the sound is not accurate. It eliminates the stutter but the actual sounds are inaccurate, plus the graphics arent smoothed and are overly sharp and a bit ugly. Compared to the smoothed graphics of the official Sony emu they look poor. PSX games run at 1/2 the res of the Xperia screen so smoothing is essential. Fpse slows to a crawl when smoothed

Fpse is good, but still has a way to go before its good enough for me to use for everything.

I'll throw in £5 UK into the bounty.

Thats about $5000 US isn't it?!

Does the XPlays native emulator really have smoothing? I did think that Crash looked better than I remembered but put that down to the small screen and the fact that last time I played crash 1 was on a large HDTV.
