the color for GsSetBgColor goes into v0 not a0 (dont know why, should actually be a0). then it works (already tested) ;)

and by the way, why do all newbies have to write that they are "noobs" into the title? if they realy want to inform everyone that they are noobs, isnt it sufficient to write it into the post itself?

it worked only once...
after a recompiling it shows the rect again!?

when i take a look at the GsSetBgColor proc in gs.inc it takes the color in a0. so what is the prob now???

thanks in advance

just to simplify that piece of code ( li is a macro and should be in macros.inc )

li a0, 0x0000FF
jal GsSetBgColor
nop

wait:
j wait
nop

this should work, afair from wiRe's ps2lib, but it was a long time I looked at it.

maybe we have different versions of the gs.inc, but mine ("GS Lib v2.0") takes the color in v0

i think i downloaded my version at wire's page. may mail me yours? hopefully it works afterwards...

i also dont know where mine is from, so i just checked the one from wire's page and its different, seems like mine is older.
i tested your code with the new one (with color in a0) - still works.

so when you set the color in a0 it doesnt work? or what exactly is your problem now?

my GsSetBgColor takes the color in a0 (look at gs.inc). the code i posted should change the bgcolor to red, but it only draws a red rect at the borders of the tv!? i also tried out an older version (1.3 i think), which takes color in v0, but there is the same problem...

ah, now i understand your problem. actually it not a problem, the program works as it should. the borders of the tv are the "background".
if you want to make the whole screen red for example you have to draw something on it. the easiest way i think would be to draw a sprite.

try add this to your program instead of the SetBgColor code:

that's confusing...
why is this proc called setbgcolor if it does not set thebackground's color????

thanks

The background on a TV is the border, because the space in the middle of the TV is the foreground.

Definition of background: The area of the C64 screen in which programmers are not allowed to draw yet do it anyways. (I think thats how the saying goes...)
