The source is included in the file on ticalc I think a lot of the basic engine is ready, the interrupt routines seem to be messing with the MENU routine in the battle engine, i'll have to check that out, and saving/loading isn't implemented yet (and since the game is so large, i've had to cut out most of the maps just to test if the engine is working), buuuut once i figure out what the interrupt is doing there shouldn't be much left to do to have a playable demo. It's the first time i've ever played it and i have to say, it's really cool It has the "digi" feel, i can see a lot of his humor/style in it.

Oh, and i have to say thanks to Hot_dog for crabcake, which has made testing it out soooo much easier, since i didn't have to worry about swapping code around to get around the 8.8k limit (and there is a loooot of code!).

EDIT: @DJ: did you ever play Robot War?

Ah i thought we could add it as an example of how to use _FlashToRAM since currently there isn't any, but thanks for the link, i hadn't seen that before

I was just asking if we could add the information/example to the _FlashToRAM wikipage.

Yeah, it's his game i'm trying to port (Digitan's), since i've always wanted to play Robot Wars but haven't had an 82 for years. I'll try asking over at MC, i don't know where/how to find Brandon W or PD.

I'm trying to port a game from the 82 to the 83/+ but none of the ROM_CALLs are equated (they all use hex addresses). I've found names to most of them in the sng.inc file, but am unsure how some of them relate (or don't) to the 83+. In particular, those around the VAT/memory:
DEL_MEM      = $258D ;Deletes a region of allocated memory: HL = address DE = size
DEL_TMP      = $3606 ;Delete temporary use memory region
INSERT_MEM   = $2258 ;Allocates a region of memory: HL = size DE = address
CREATE_TMP   = $38D0 ;Create temporary use memory regionWhat's the difference between the the MEM and TMP versions? The program is trying to allocate memory for something but it always crashes here. It's using the CREATE_TMP/DEL_TMP routines. There's a little bit of info here:
http://tifreakware.net/tutorials/multi/unification.html#part05
It seems like the program is trying to recopy itself into a new program.. or something along those lines. I haven't had time to look through it too closely yet, but i've noticed in the emulator that after the ChkFindSym it returns the VAT entry for the program in HL, which seems to be correct, but the address in de pointing to the data points to somewhere in  $FEXX. Is it that the shell (zStart) is doing something funny? Because i don't see any data. I'm not too familiar with the memory routines or the structure of the calculator, i think i could just _InsertMem to the end of the program (it's for saved games), but it's such a large program (>22k) but i can't seem to find it in memory! I think in the end i will try to convert it into an app and just use app vars to save the games, but i wanted to try and get things up and running first since i don't feel like trudging through all the complications that would bring (SMC, text routines, multiple pages, etc.) just yet.

Wow, that looks a whole lot better. The only thing that makes it look square-ish are those square boxes in the middle, but really the whole set looks very nice together. For the diagonal sprites, will you be able to walk diagonally? or will the hit detection for those sprites take up the entire square?

Other ideas:
-make a mix of phoenix/pong, where you have some enemies on screen trying to shoot you while you have to keep the ball alive.
-powerups that you have to hit with the ball (so either you or your opponent can get them, depending on who it was that hit the ball).
-expanding on Art_of_camelot's gun idea, give each player a certain amount of health and you can beat them either by making them miss the ball or killing them, you could also use the gun to change the ball's direction
-randomly changing spots on the board that make the ball "invisible", so that you can't see it until it leaves that area

There's lots more you can do, it just depends how much time you want to spend on it

*Doh* i just realized this wasn't for the 83/+ and now i'm really bummed out. That new screenshot looks much better! My only suggestion i can think of is larger more complex levels.
