i thought id get in on the game modding front… i used claude code (sonnet 5.5 in med mode) to fully decompile and label the functions in Rally II, and then speed up its routines, eg, the RLE cars are now proper sprites with blitter, which speeds the game up a few fps and its quite noticeable when playing!..changed the colors of the cars (easier to see at night!)..and added a proper loading screen!..and saving and loading tracks to/from disk (it was hard coded to tape)… EDIT: oh added another layer of parallax, the hills move faster than the clouds! Before: ![play_00](https://forum.cpcwiki.eu/uploads/default/original/2X/9/9eaa451eb6a536c9c85e378345f7393d1d9ed61a.jpeg) After: ![pr_14](https://forum.cpcwiki.eu/uploads/default/original/2X/f/f687e1d684a748f6103cea33a766e6da26749ae8.jpeg) Loading Screen: ![image](https://forum.cpcwiki.eu/uploads/default/original/2X/7/776beefc1c547288d62dd94f9a6356657337fa4e.jpeg) [rally2\_rebooted.dsk](https://forum.cpcwiki.eu/uploads/short-url/sslMZ6XWOZVvjjcHTpa2GCRRcjD.dsk) (190.3 KB) it only runs on 6128! the 2nd bank is used to fit in the car sprite routines (moves car sprites to 2nd bank) i still want to add road side sprites, but im almost at limits for the week! EDIT: updated with keyboard redefine, so you can use in the forums emulator! (for some reason RVMPlayer crashes on the title screen when i enable the redefined keys function, but it works on other emulators)..so the version uploaded here has the redefined disabled..joystick works tho! im out of credit so cant update it further till next weekend! Claude Breakdown: Sonnet 5.5 Input:582 Output: 94.2k Cache read: 139.5M Cache write: 1.5M and 10% of weekly limit for all the changes… ---

I can’t get the ‘redefine keys’ option to work. I have tested the game in _AMSpiriT_, _CaPriCe Forever_, _CPCEC_ and _WinAPE_, but pressing K on the attract screen as requested does nothing. ---

i got a free reset on Claude!.. so i was able to get it to fix the key redefine routines i also added a car color select on the title screen, by using up/down to change player car color, and left/right to select opponent car color, and opponent car is now shown beside the player car on the title screen.. ![image](https://forum.cpcwiki.eu/uploads/default/original/2X/0/08148488c50526116f60f789720c0852619f0d2c.jpeg) ![image](https://forum.cpcwiki.eu/uploads/default/original/2X/9/94ba8faed08af0438492f3ca18f53cbcb2e253f4.jpeg) i also added track side sprites..with collision that fixes the drive on the right kerb cheat!.. [rally2\_rebooted.dsk](https://forum.cpcwiki.eu/uploads/short-url/6oCBjsJZRGCEisA0aqU3rH4ZICe.dsk) (190.3 KB) (still crashes RVMplayer!) im going to ask someone if they could make some better sprites (i borrowed these from crazy cars2) so this is not the final version! ---

heres a quick vid, as you can see, bridge, and beach stages dont have track side sprites yet, i didnt want to have trees etc on the water!..if you can make it to the desert stage (the snow stage is harrrd now!)…you will see cacti instead of trees/bushes..
