Awesome new release :)

Any chance of releasing a simple how-to for using the PSP remote that came with it?

I think this may be cool for some tetris like games :)

without a shadow of a doubt this has to be the killer release of the year.

/me hopes for a Dreamcast port one day

Hope this isn't too off topic or anything, but the max image size is 512x512? Dang. I had just finished drawing up a game idea that requred a 960x544 image, which the player scrolled around on (4x the size of the psp screen).

Do I have to scrap my idea? Or is there a way to create an image of that size, but only blit a 480x272 area of the image to screen?

Why not load the map up as tiles?

Even if none of your map could be reproduced as smaller tiles (e.g. 32x32) you could split your map into several 512x512 files.

i have code on my page which uses 3 500x272px images which are scrolling (you may easily expand the code to add images above/below)
so my width is 1500px, more than you need ;)
loading the images takes some time (gary tested it on psp, i didn't)

greets

That's an option. It would just be so much more elegant to have the larger image size;) I'm afraid the game might be complex enough without having to stitch images together. Don't want to have it running at any slower fps than necessary. I know an extra 4 lines of code isn't much, but every little bit counts.

well my code uses 2 blits, which is the minimum for that job ;)
and its running smooth (and just requires an variable for x-positioning)
(and y if you extend it)

note: you may post the extended version here, then i would upload it (give credits for sure!)

Thanks for the offer. I have my own webspace that I'll be uploading my stuff to. Of course, I'll post links. I'm just in the begining stages of laying down the script though. I did a couple test programs to get the hang of LUA. Nothing worth posting though, just some simple image blits and so forth.

Where can I find a binary version of Lua Player please ??
I don't have the pspsdk installed and don't intend to so I think it would be cool to have a ready-to-use Lua Player.

its already compiled, when you do not load the source ;)

Err.... I don't understand. What do you mean by "its already compiled" ?? If so, where is the compiled version of Lua Player ??
I thought that a binary version of Lua Player would be something like an EBOOT.PBP file.

Read the first post in this thread. There you'll be able to locate the binaries.

Ok found it.
Thanks to LuMo and KawaGeo.
