Cool compo! Maybe I'll give a shot at coding a little LCD game :)

I got to use BlueJ in school too. Didn't like it very much though, then again I'm not a big fan of Java. BlueJ is just an IDE and javavm will run any java thrown at it provided it observes limitations mentioned earlier in this thread. So yeah, it'll work just fine :)

Well I found that register controlled shifts does take 1 more cycle, but I have not found that you can only shift max 3 in an imbedded one. I'm starting to get pretty sure that you can make any imbedded shift for free. I was just hoping for some clarification :)

How can that be? The only reason I can think of is that the shift amount doesn't fit in the instruction and you'd have to shift by an amount stored in a register (which does costs one more cycle), but ALU instructions (e.g. ADD, SUB, AND, OR ...) have 8 bits to store the amount which is enough...

I must have underestimated it's size, I was thinking it'd be at most ~50 cycles per iteration which would give ~10 ms per frame. I checked it out and it seems that you can give it any bit-rotation of values up to 2^8, this is good news for your case, e.g. you should be able to give it...

Shifts are free, & and | take 1 cycle. Ah ok, I should warn you though premature optimization can be a waste of time there will proberably be bigger fish to fry than this little bugger. Don't let me discourage you though, learning and practicing optimization is a good idea. I don't think...

I don't think you'll get it much faster, it's pretty simple code so the compiler should do a good job of optimizing it. If you want it faster you'll either need figure out how to make the blitter do the depth conversion since this takes the most of your time or skip it completely (if that's an...

I guess it would be possible to set up a compression loop-back device and use that. I don't think it's worth the hassle though. Also, you would have to be pretty linux savvy to pull it off.

Oh, this is a cool idea! I would also like to have Lisp on the gp2x, to bad the only common lisp compiler that supports arm is gcl (which uses gcc to do it's dirty work). Gcl isn't supported by cffi or uffi so there's a lot of bindings to libs that can't be used :(. But I'm afraid to test...

What Squidge said. I would also recommend you use gcc's -funroll-loops flag, I think it could do wonders for your loop. A great book about coding optimized for ARM is "ARM System Developer's Guide" there are tons of hints and optimized primitive rutines to use for both C and ASM, you'll need...

So does mine. Sorry guys but there's just no way you can't beat Hammy the Hamster :rolleyes:

I've never used -rpath before but quick look in the man pages suggested that it should be passed like this -Xlinker -rpath -Xlinker /usr/local/gp2xdev/lib You can only pass one argument per -Xlinker option or it will be passed as a single argument as if it had been quoted, which seems to have...

Well judging from the path to the ld executable you're using a linker for x86 binaries. You'll need to use the linker provided by the cross compilation tool chain. I think setting the environment variable LD to the correct ld executable should fix it, e.g. something like: export LD=gp2x-ld...

I think this is a grand idea! Developers have much more info when it comes to how much time their apps consume, so they should be the ones doing it. Ideally it should be done on the fly, using the lowest clock speed that lets the app run at correct fps and letting the users specify a max...

Well, according to this rule you would have to make the entire program by yourself. So basically clones are allowed because even if they similar to another game the author made everything himself and ports because they rely on code and media not made by himself are disallowed. The port banning...

Well ok I guess. :rolleyes: Maybe I'll make my own cutsie RTS in the future, I already came up with the name "Flowers to die for" might as well follow through :P

Sounds great, good luck have fun and all that. Now on to the real issue, will Platoons contain flowers to die for? ;)

This is a bit of a bump, but I just have to say how much I like the idea of a war fought over flowers. :D Anyway I was just reading through the thread because I missed most of it and was wodering what became of it. Seems like you guys managed quite a bit, keep up the good work. Also since I...

I took a closer look on their home page (which worked for me now) and the stand alone executables does require the VB runtime. So depending on how much of the engine is in VB, porting it is anything from very hard to nightmareish.

Well right now they are hardcoded but in a way so that it will be easy to move it out to a configuration file eventually. The implementation was based on SDL Sand (which had it hardcoded in an ugly way), as it is now it's inspired by, but a bit different then wxSand. So it should be possible to...
