Post Hydra / PAL
First all demos works fine on my 2 TVs (NTSC, PAL)! How ever to do the right settings for PAL, I should set the TV mode to PAL ! I have changed : tvparams (Long %0001 'mode) is there other settings I should change (Frequency ?)

Ps: I would like to fill the OFFSCREEN_BUFFER with a specific color (say Bleu : $1B) do you have any suggestion please?

Thanks

First, I am not sure what driver you are using, your setup, etc. be specific, what exactly are you doing? Secondly, go to the parallax HYDRA forums and download some PAL game examples from the master project list and then use those drivers, we know they work, and we know they are up to date.

All right sir, I will go to parallax forum.
What I’m doing is testing on of your demo’s “Scrolling Text Drawing Demo” and I just want to have the background of the screen all in blue and I’m using PAL TV.

Thanks, Sir.

This is what I did to test

PUB clear2

'' Clear bitmap

setcommand(_loop, 0) 'make sure last command finished

'longfill(bitmap_base, %%0000_1_010, bitmap_longs) 'fill bitmap blue
longfill(bitmap_base, colors[1], bitmap_longs) 'fill bitmap

Hmmm -- well, first thing is you need to get things to work on a NTSC TV then port to PAL, so you have a frame of reference. I didn't write the TV.spin driver, Chip did from parallax, he did test it on PAL, however, some of the bit settings are wrong on it and you need to make sure things work, so like I said, best thing is to just goto the parallax object exchange and download the latest tv driver (if you want to use that) and or just try one of the 100 demos people wrote for the HYDRA on the master project list, MANY support PAL --

Looking at the TV_DRV_010.spin driver, seems like 1 bit in tv_mode controls the PAL/NTSC mode, so do this just take a working demo like my asteroids or something that uses the NTSC mode, run that, then CHANGE that one bit -- see what happens, should work --
