Hacking [RELEASE] SDLPoP-Vita, an open source of Prince of Persia for VITA

[usineur]

Hi there,

I just wrote a port of SDLPoP to the PS Vita. SDLPoP is an open source engine rewriting of the Prince of Persia dos game.

The port is in early stage, do not hesitate to report bugs here.

Here you can find everything you need to install and run it: https://github.com/usineur/SDLPoP-Vita/releases/tag/vita-1.0

And you can see the prince in action here

This is awesome. Thanks
In the old days, we just carried our Apple 2e's around with a generator, and called that portable. Joking... We couldn't afford the Apple 2e or the generator. I played this at school as a kid.

Great release, thank you

I just played for 30 mins or so with no problems, if I encounter any bugs I'll let you know.
It took me a few deaths to realise that holding X then pressing left or right only does a single 'careful step', then returns to normal walking even if X is held down. It's been a long time since I played the original POP so this is most likely the expected behaviour

Good luck in the GekiHEN contest, I hope a mod there approved the entry before you posted here. If not then I saw nothing

Mine is not working for some reason...
Instal the vpk... put the prince folder in ux0/data folder.... i get the loading phrase for a quick second than it disappears but the game does not load.

Can you list the content of your ux0:/data/prince in a pastebin link or whatever ?

Just to be sure there is nothing missing...

Excellent work! Are you planning to bring us The Flame and the Shadow some day??

thanks usineur0 btw, how hard would it be to remap the jump button to O instead of up on the dpad? its a pain to play like this
EDIT: Never mind, got used to it. But it would be nice to create something like a button config.

I dont think so and I'm also working on an other port for now

I just release a new version: https://github.com/usineur/SDLPoP-Vita/releases/tag/vita-1.1

Main changes: loading time is deeply reduced and the game is displayed in real fullscreen now

Done.

Do you have to press X again every time you want to take a careful step? Because if a keep it pressed and then press left/right two times it just runs...

It's a bug on my side. Latest commit fixes the problem.

Would you release a compiled .vpk?

It is. But don't let you take off from the tight time limit (at least it's tight if you play it the first time).

Would you release a compiled .vpk?

There is one here: https://github.com/usineur/SDLPoP-Vita/releases

That's it. This release contains the fix.

Just passed the game on second attemp with first version. There a some very small timing glitches, espacially when fighting their guards (did pass PoP approx. 100 times within all these years). Unfortunately i can't enter any name in the lack of a keyboard. Softkey feature of the Vita would be nice.
However mate, let me tell you, your work is awesome... i allways loved this game and playing it on the vita now feels just incredible. Thank you very very much!

appendix... on the original PoP... if you have trap plates which would fall off... making them shake three times would cause them to fall. Didn't compile SDL PoP for linux anyway, so i can't tell if this issue is with your Vita Port or if it is SDL PoP related.

Just figured out an 1.1 issue. When i hit "PS" button to pause the game, melodical sound stops working. It did work on v1 though. Also i would love to center 4:3 instead of strech to 16:9... or just strech it half way to make it look much bether. However, still an awesome job. Thanks alot.

I will add this feature soon. In fact, the code is already written, but I need to refactor it.

Thank you. The main work is due to NavyD, he deserves all the credit for the engine.
I just made the Vita port and a little enhancement for the music support.

I don't know the original behaviour, but I'm pretty sure it comes from the SDLPoP engine. Take a look at the doc/Readme.txt file into the repository, maybe you could find informations about this.

The latest commit I just pushed on my github fixes that problem. Thank you to point me this problem, I didn't see it.

I will make a new release when the keyboard support will be definitively integrated.
