Heaven/TQA Posted May 18, 2004 Share Posted May 18, 2004 ok folks... just played around little bit with my old memories ("how the hell does append work on atari... ) here is the 1st version of reworked thrust binary with g2f title screen... it's still beta status because of... - g2f intro crashes after pressing start - no thrust RMT music available - g2f screen is not finished as the bad lines are not covered yet maybe dely can send me some light why it crashes... this thrust g2f is done in GED mode so its a big unrolled loop... and it switches off ROM as well... so i exit the code with this... lda 53279 cmp #6 beq endloop jmp LOOP endloop mva #0 ^4e sta 53248 sta 53249 sta 53250 sta 53251 sta 53252 sta 53253 sta 53254 sta 53255 sta ^40 mva #$ff ^31 mva #$40 ^4e endend rts and as you can see... it seems to crash and does not load the 2nd part... the intro is started with $2e2 and the main thrust game with $2e0... so it should work... you can analyse the binary with XHEAD for the segments... any help much appreciated. thrusti.zip Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted May 18, 2004 Author Share Posted May 18, 2004 ok... simple idea...i merged all together... and after loading all stuff together 1st the g2f intro is started and after pressing start it jmps to $5600 where thrust is started... but same crash here as well... g2f code $2000 g2f data $3000-$3fff $4000 pmbase $5400-$bfff thrust (ram save, thrust can be started at $5600) no packing at the moment... thrust_.zip Quote Link to comment Share on other sites More sharing options...
emkay Posted May 18, 2004 Share Posted May 18, 2004 Is your code switching off full ANTIC DMA when jumping to the "2nd" part? Another possibility is that the game does use some registers by defaults and the G2F code does set them to another value ? Quote Link to comment Share on other sites More sharing options...
bjk7382 Posted May 19, 2004 Share Posted May 19, 2004 So are you just working on the title screen of Thrust? I think the gameplay needs some changes also. Such as how jerky the ship moves when you have the ball in tow. Also there seems to be no gravity and it just doesn't feel right when playing it. Some type of joystick control would be great.

ndary Posted May 19, 2004 Share Posted May 19, 2004 I remeber seen a patched version of THRUST that replace the controls to joystic control.. but i liked the original controls... attached is a picture of a Thrust cartridge i made in the past..
