Heaven/TQA Posted July 4, 2010 Share Posted July 4, 2010 After great defeat of Argentina yesterday I thought I can give Gridrunner last touches before releasing the "final" release candidate... In Atari800 Mac emulator I am not able to track down the "white" bar fx at the top of the screen of the NTSC version of the game intro. Can someone please have a look if this is an emulator issue or if this is happening on real hardware, too. before spending too much time to track down the "bug". game_intro.xex 2.zip Quote Link to comment Share on other sites More sharing options...
Rybags Posted July 4, 2010 Share Posted July 4, 2010 Does it in PAL in the emu as well. Might be a bit easier to debug if it looped rather than just running once or twice. Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 4, 2010 Author Share Posted July 4, 2010 shit... what the hell is it? aah. I am demo coder...so rather to fix it... I will implement an DLI to hide that garbage... Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 4, 2010 Author Share Posted July 4, 2010 well.... never touch color registers in a draw loop... seems it was debugging code.. game_intro.xex 3.zip Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 4, 2010 Author Share Posted July 4, 2010 well... this is the first packed version incl. NTSC check. please run it on the real machine and let me know what you discover... I spotted green missle garbage in the game. the relocator for the vic code (game code will be put at $1000-$1dff after game loaded for DOS loading) and the pm bug i am not able to track down because the game always crashes when i am now inserting code. do not know what the issue is here as imho there is no code overlapping... gridrunner_rc.xex.zip Quote Link to comment Share on other sites More sharing options...
Roydea6 Posted July 4, 2010 Share Posted July 4, 2010 I spotted NO garbage in the game, except the unpacking streaks. This file gets all the way into the Title screen, I waited a bit to see if it would continue --- then press START, TRIGGER, SHIFT, ETC... Shift caused the game to goto black screen and then nothing. The next try I pressed TAB and got IO noises then black screen. Is there a continue key? NTSC 240K Rambo upgrade. Quote Link to comment Share on other sites More sharing options...

emkay Posted July 4, 2010 Share Posted July 4, 2010 Nice presentation. This really was missed back in those days. The picture has some logic bugs, but it's better than nothing I also wonder about the music style, it's a good decision. The game, well, somehow I'd prefer the "Atari original" , but it's not my type of "wanted" games at all Well, good work, on the wrong game Quote Link to comment Share on other sites More sharing options...

I got this put into a game dos[mypdos4.04] atr and ran on original 800xl NTSC 196K rambo.. NO garbage until after I press RETURN key and game continues to load. At the game screen I have a green line vertical center of screen. All else is just great, I played several screens and then reloaded and got the same green line. TRIG and START key didn't start game loading only RETURN key loaded game. Quote Link to comment Share on other sites More sharing options...
Rybags Posted July 5, 2010 Share Posted July 5, 2010 Don't take this the wrong way... but the game risks becoming bloatware, given that the original VIC version worked in under 5K or whatever it was. I reckon you should just polish up what you've got. Improve the sound effects and be done with it. Quote Link to comment Share on other sites More sharing options...

phaeron Posted July 5, 2010 Share Posted July 5, 2010 ps. the green line in the main screen is the issue. I must be missing something, but it looks like the green line is just a missile left over from the title screen...?

Some - simple/ stupid questions approaching... Main title image looks great - what gr mode it uses? And is that result of conversion form pc trough some utility? Something like bmp2atari_colored_image+DL_code+asm_routines_for_color_changing should be great. At least for me. Game itself is just another shoot em - maybe it can get some runs on real HW but this time I'm using only emulator. Quote Link to comment Share on other sites More sharing options...

I am clearing all data when exiting the G2F. Maybe this helps then. and repositioning at pos. 0 does not help much as it might be visible on emulators who show the whole scanline.

Heaven/TQA Posted July 11, 2010 Author Share Posted July 11, 2010 ok. tracked down the routine which causes all the crashes... it is the sample IRQ. the sample player is an timer IRQ. How can I securily switching off the IRQ when the sample played? simply write 0 to IRQEN? Quote Link to comment Share on other sites More sharing options...
Rybags Posted July 11, 2010 Share Posted July 11, 2010 Yes, just disable whatever bits for stuff not wanted. Default value is $C0 (Break + keys enabled). Don't forget the shadow too (POKMSK @ $10) - some OS stuff will copy that back to IRQEN. Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted July 14, 2010 Share Posted July 14, 2010 I am curious, are you re making the game? I have this on cartridge from HES. Crazy hard game! Very fast. Or is it a new game Completely? Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted July 14, 2010 Share Posted July 14, 2010 (edited) Interesting, I remember my pal Jeff had a commodore and we compared this game side by side as well as flight simulator. Griddrunner won on the Atari but Flight sim was a toss up. The Atari loaded flight sim faster. And gridrunner was instant as it was a cartridge. Am I understand it the game will be made better graphically and enhance the gameplay features adding some new ways to blast things from the grid? Mintner has his Atari version posted for download at his sight, you might want to check that out http://www.llamasoft.co.uk/lc-8bit.php click the photo of the box and it will download it. http://www.yakyak.org/viewtopic.php?f=39&t=77627 new gridrunner by mintner on new systems Gridrunner Revolutions Edited July 14, 2010 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted July 14, 2010 Author Share Posted July 14, 2010 I guess I make a FAQ page soon... the game is the original VIC20 version run on A8 with some enhancements. No game play changes nor big gfx changes except for some DLIs. Title screen plus music + sample "Gridrunner" added. Why? Because I hate the A8/C64 versions and one of my first games was Gridrunner on the VIC20... Quote Link to comment Share on other sites More sharing options...

I have full source code of the game... what about an 7800 port? can be done similar way... attach patches for the gfx (draw sprite, sound routines). 7800 version could be done faster as no color "patches" needed as you anyway use the DLLs.

Yep! Its certainly possible. I'm not sure how the game's G2F title page will look using the 7800's palette and G2F converter. How much of zero page is used? 7800 version would be welcomed, where is Groovybee when you need him?! Here! Quote Link to comment Share on other sites More sharing options...
