thx ranman, i have the path set now, but when i run it, it still saids i need to set enviornmental variable for TISDCC dir

Try this Dragon_Lance, Start -> Control Panel -> System - Click on the Advanced tab - Click on Environment variables - Click on New, the following window will come up  - Type in the Variable Name - TISDCC_DIR - Type in the Variable Value - c:\tisdcc - Click Ok - Click on New - Type in the Variable Name - TISDCC_CC - Type in the Variable Value - cl (for Microsoft C Compiler) - or Type in the Variable Value - gcc (for GNU C Compiler) - Click Ok, Ok, Ok Note: the variable value is the path, this can be any directory where tisdcc is installed. This readme file is a little confusing. Hope this helps! :)  
C runs just as fast as ASM until the ASM is super-optimized, in which case, the difference is minute. The people on MaxCoderz obviously have not programmed in it and compared it to an ASM program that does the same thing.
yeah, I assume they want to compare with a C fps, and a ASM fps game with grayscale polygon 3D graphics :S
@Dragon Lance: I home you make some awesome games in C... Maybe you could make like tutorial programs for n00bs, like with EZAsm. >D
So, DL...how hard is C to code, and what functions oes it support?
ummm, haven't really started yet, gonna start after zelda. I read some of the tutorial that Ranman recommended, i get C for the comp. But wat are the specifics once u translate to CAlc? btw, i looked at the test demo included with demo in C, it actually looks understandable %)
I dont mean to be spammy SPAM SPAM SPAM!!!
But I think another program is worth considering, EZAsm. I have programmed a pong game in it, in which will be the basis of my next project
GO TI84Silver!!
SPAM!!

I'm glad to see you are looking into this.
If you can program C for a computer, it should be easy to do it for a calc (as long as the differences are explained in the documentation of the compiler, like in TIGCC).
Anyway, you will have to program more carfully. A computer won't claim about a lot of unused variables, arrays that are way bigger than they are needed... the calculator will because of its strongly limited RAM.
no expanation is given, all it saids is it uses SDCC's z80 compiler :(
maybe there is doc about this compiler somewhere

http://sdcc.sourceforge.net/
This compiler for Z80 calcs should do all of the necessary things to make an executable for the calc.
It appears that it does not provide full support of the Standard C library. So, some things most C programmers take for granted will not be available. However, you can easily make your own substitute function.

If I knew how to make a C compiler, I'd try to improve upon it. But seeing as I can't master C or z80 ASM, and I possibly never will (see post in Ultima Thread as to why) I don't think I'd ever be able to do that.
What do you mean by standard C functions? Computer C and high level equivalents?
but don't give up trying, you'll get there someday... ;)
edit: i just browsed through the documentation of SDCC, and it barely even mentions z80. still have no idea of calculater specific stuff. :dang:
@ranman:when u have some freetime away from Ultima, do u think that u can try to explain to us noobs how SDCC works and the specifics of the z80 processor, (it did mention registers, but that's about all), like buffers,etc...thanks a bunch if you could >D

Umm... that's like a basic requirement if you want to make good ASM.
I lost my copy of the z80instructionset and specifications in my old computer. I never got a chance to read it, but it's really not that bad.
I just wish there was more like port documentation
Does anybody know what happened to MC? I can't find the site anymore.

I will sure give it a shot. I'll take a more in-depth look at SDCC and get back with you.
I actually have a Z80 instruction manual lying around here somewhere. Maybe it is time for me to take a look at that too.
i think Maxcoders domain is renewing its domain, so can't acess it from there. just go to google and type "maxcoderz forums" and it should give you a direct link. and thanks a lot ranman, perhaps if u could get an 83+, you can also code C for z80 :D

This looks interesting. I think Ill give it a try (with my limited C/C++ knowledge).
How exactly do compilers work anyways? I know they are converting to machine language, but how do you build the compiler if you couldn't compile it in the first place?
hm... maybe build it directly in machine language? %)
well, there has to be a way or we
hey guys, has anyone tried out the other C compiler that compiles Z80 code, Z88DK ? I was just browsing wikipedia encyclopedia and i came across it.
nope never tried it, im heard the code was crappy :(
anyone tried API yet?
API will bloat your code if you use everything. Right now, I think I'll just be using API's sprite routines for DEM because it's much easier than trying to make my own that are really slow.
Overall, API is really helpful because it's like additional r0m calls, or xlib functions.
I still haven't really tried it though.
i tried API, it is AWESOME!!!! especially for noobie asm programmers like us xlibman ;) . the big plus i see for it is there is a var.read(x) function and a var.write(x) function. with the use of xlib BASIC programs, u can create an ASM program using API as a helper program, for like quick math and stuff. unfortunantly, experimenting with API, i haven't gotton the normal sprites to work yet :(
@liazon: wat would u exactly mean by API bloats ur code. Doesn't API not include the routines u don't use, thus only including useful routines...

*points
Come to think of it, all of the routines are a compilation of the best of the best well known routines. Using it parts of it (not necessarily with macros) will definitely improve anybody's ASM program. Granted, you will never understand how they work, but it's a lot of good routines.
Most notable routines that I hope to use for DEM:
Sigma's sprite routines; masked, AND, OR, and XOR logic
Jim e's RGP
i guess the trick is to use as less routines as possible with api, right?

Well... I guess... use what you need to use. If you need to use it, then you need to use it. If you don't use it, then you will have to code your own function to do the same thing. If you can make it faster or take less memory... then maybe going with your own function is the better choice. :)
But I can't think of me, an ASM newbie, coding a sprite routine faster than sigma's or Jim e's RGP.
if sigma's routine is faster, why not replace ionPutSprite with it?
