I use this code to sleep for x seconds
void WaitSeconds(int seconds)
{
REG_TM3CNT = TIME_FREQUENCY_1024 | TIME_ENABLE;
REG_TM3D = 0;
while(seconds--)
{
while(REG_TM3D <= 16386){}
REG_TM3D = 0;
}
}
it works great with Boycott Advance, but in VBA it will only sleep for one seconds, no matter how many seconds I tell it to wait..is there any setting in VBA I got to do or a bug or something?

I remember having trouble with timers for this sort of thing on VBA - have you tested this on hardware as well?
In the end, I gave up and used vblank as the "wait" timing. It's the best method for a couple of reasons: it works as predicted on hardware and all emulators and it saves batteries by not spin waiting - an empty "while {}" is the equivalent of having the accelerator pressed with the hand brake on!

You have to turn off the timer before you can write anything to it's "counter" register, if you even _can_ write to it's counter-register, I don't remember. Besides, if you are waiting for seconds, or even 1/60 of a second you are probably better of counting vblanks and use the timer for something else.

Before all that, check if you're missing some "volatile" declarations on the REG_TIMER stuff. If you don't do that, no matter what you put in the address, the machine will never check it. Dovoto's #include files didn't have them, and I had a few headaches because of that.
