You don''t need the óriginal developpers hardware' to do something with the 7800. All you need is 6502 asm knowledge (which sound more difficult then it actually is) and some knowledge about the 7800 (video)hardware. I know 6502 and program things for the atari 8 bit computers, and i read a few day's ago information about the 7800.....but there isn't enough documentation about the 7800 maria video chip for me........ Thelen

I was using CodeGenie with great pleasure, but now my trial has expired..........and every minute i get a nitice of that.... any suggestions for a good editor ? Thelen

That's very sad........Was pirating a big problem for the atari 8 bit ? and not for the other systems ? Thelen

I was thinking, why wasn't there released an atari 8 bit version of Impossible mission ? A bit strange, on almost all homecomputers it was released.......even later on the 7800, ST and Amiga.. Thelen

I have uninstalled my video driver, and the problem is gone ! (but also my resolution and colors ) Thelen

Thanks guys, I was using codegenie, and I was using Unix mode. changed it to dos, but that didn't help. (why is it standard on unix mode ??) the problem was, I was using vers. 2.5.1, and I upgraded to 2.5.2, and the problem was solved !! one other thing, I don't have buyed or registered codegenie, and when i push the arrow UP button i get The message (pop-up) Nvidia 4 in a box, i close it, and some time later when i push arrow up, it appears again. I'm getting sick of that. Is it because i don't have registered it ? Thanks, Thelen

I have been thinking about this too. A compact flash cart can work in various modes, and one of them is a real IDE mode. It would be great to have 512 Mb CF inside.....But wil it work ? Has anyone tested some other IDE media beside a harddisk ? a zip drive ? Thelen

dead bug chips Thelen

for the first time I wanted to use an include, since my program was getting a little unstructured. so in my main program I typed ICL 'vleer' and I made a file with the name vleer.asx with some source in it. but the problem is, I get a error : Line too long....i don't get it... When I cut three lines of the source code (doesn't matter which ones) it works ok. source : vleer LDX #0 STX VLEENR ;VLLOOP LDX VLEENR ; LDA VLEEON,X ; BNE VLEC1 ; LDA #$B0 ; STA VLEEPH ; LDA #$20 ; STA VLEEPL ; LDA #1 ; STA VLEEON ; JSR VLEBACK ; ; ;VLEC1 ; VLEBACK LDX VLEENR LDA VLEEPH,X TAY LDA VLEEPL,X TAX JSR CHECPOS STA TMP1 LDY #$A0 LDX #$00 STX TMP2 I really don't understand why my lines are too long, and when i cut random three lines, it say's it's ok. Maybe i'm doing something very stupid, but i can't find it..... I use XAMS and Codegenie Thanks, thelen

I have done a memory upgrade to 320K on an 800XE, which is working properly as far i know, Numen is working on it, It's really great to see this demo on the real hardware !! (I have also soldered in a good gtia ) has somebody some ram test software for me ? to check if everything is ok.... Thanks, Thelen

well i'm from europe, and i haven't heard of a badlands game here for the 8 bit. But I think what you guy's don't have in the U.S whe won't have either here.... Thelen

This is really looking good !!!! that interlacing is a nice idea !, and lots of sprites ! Thelen

Yes you're right Heaven, I did move some code from $B000 to $C000, just to get some screen data temporaly moved...Thanks, i was thinking 'Professional' ) Thanks, Thelen

Thanks man( I didn't have time to test it before) it works, but the color changed only 1 time on the scanline.....i want at leat three and I am using XASM, and it says to me : WARNING professional loader needed, what does that mean ? Thanks, Thelen

well, it depends on the price, and what can be done with it.. Thelen

If you use the Myide OS eprom, you can boot direct from your harddisk. That's very nice, no need for a diskdrive anymore. Thelen

Thanks, but that's not what i'm looking for, that example changes the screencolor only once. I want to change the color register a few times on the same scanline, so that on one scanline the background has multiple colors Thelen

yes i'm using the hardware register, COLBK $D01A, but i get no color variation on the same scanline, only at the scanlines underneath..... Thelen

I've tested it on the emulator and on the real hardware, but i don't understand how to do it.... ? Thelen

I was doing some little experiments on the atari 8 bit, but it just won't work.. Is it possible to change a color register multiple times on the same scanline ? I was thinking it should be possible. let's say change the background color 10 times on the same scanline : sta wsync ldx #0 loop stx colbk inx cpx #10 bne loop and I run this from in a DLI is this possinle ? and how ? Thanks, Thelen

If cleaning up the cart slot doesn't help (which I think) your TIA chip went bad. The TIA chip does all those sprite (player/missile) things. Hope the cleaning will help ! Thelen

I think it isn't made yet, and it won't be made so soon. that's because the atari st diskdrives are just normal 3.5'' 720KB pc standart drives. so you have to emulate a normal diskdrive. Off course it can be done, but it seems for me more difficult then a sio2pc circuit. Thelen

Sounds very nice ! Thelen

thanks, thanks ! I have re-used my players!!!....and I understand it !!!. actually its very simple with a DLI. And yes, changing the color is simple too (off course, when i think about it now) Thelen

thanks guys. I think I understand it now (haven't tried anything yet) I was doing things with pmbase switching....and changing the Pcolors....haha. The only thing is off course that if I re-use player0 the re-used player will have thesame color as player0, or I should use a kernel... Thelen
