Very impressive, almost hard to believe it can be done on Roku!

I'm guessing you can't move and jump at the same time? Seems like that's always a difficult hurdle with not being able to receive multiple buttons simultaneously.

Very cool though. Never realized the original was open source.

As you can see in the video, we can jump when running, because of the "inercia" the original algorithm had implemented, the only limitation is the "shift" key that allow you to walk or hang, so I had to implement it as a on/off toggle button, that works ok, if you train you can run, jump and hang as you do in a PC keyboard.

This is a port from a 1989 ("before you were born" :mrgreenSmiley Happy game for Apple ][, whose keyboard was even more limited (as explained here - basically buffer of length 1, with only key-down codes). But even so, developers found a way having key combos

Re: New project Prince of Persia (soon will be open sourced)

This is truly amazing. I'm old enough to remember it as one of the first "good" games for the PC. Never tried it on an Apple (and never will :mrgreen: ).

What I'm doing is nothing compared to what this guy did:
popc64.blogspot.com

Before the author release the code, this guy disassembled the Apple II code, and ported it to Commodore 64, the blog describes the process.

Holly FAQ! Smiley Tongue
This is amazing - to see it working, it is.

After a quick check, seems to me to work reasonably well on Roku LT and RokuTV too, so 3xxx and 5xxx models should be able to run it too, not only 4xxx! I used infrared remotes - worked fine. But one of them does not have "Replay", so i have suggestion to accommodate for that, i.e. don't rely on A/B/Replay buttons being present, use OK/*/Back instead.

The idea of showing 2x2 and 3x3 rooms on screen is interesting... not sure a quite buy into it, since part of the game challenge was keeping (mental or not) map of the dungeon, this makes it easier - suppose i am "originalist". Also the non-4xxx players seem rather "syrupy" in such modes.

Can the 1x1 (original) mode be zoomed 2x? Thus it will thereabout fit the screen, currently image seems small centered.

I will do it

This is on my backlog since the beginning, the issue is that Roku 2D API does not have a simple way to do this, I will have to scale every sprite and save on temp, other game engines has this as generic setting.
