Motocross Maniacs (U) [!].gb
The original version of the game.
Konami GB Collection Vol.3 (E) [C][!].gbc (The game is renamed to "Bikers")
Same as the original version, but with colors. Unfortunately it runs at half the speed compared to other versions, so I think this shouldn't be used.
Konami Collection 2 (J) [S].gb
Same as the original version and with SGB border. The colors are slightly brighter.I made a small TAS for fun: http://www.youtube.com/watch?v=K3TbboLTzB0
- If you cross a checkpoint ramp, and then use nitros to boost yourself back, the ramp will update to say "GOAL" but it will unfortunately not function as a goal. :/
When going back, you can collect items from lap 2. Those collected items won't be there when you actually do lap 2.
Here is a gif of it. I tried going further back, and also tried going a little further beyond the goal before going back, but it didn't trigger the finish. I wasn't yet able to find addresses that I could edit for position and nitro, so I'm a bit limited in how much I can test this stuff...
Item slot addresses at $CA00~$CAFF (System Bus).
Each slot tells (1byte each): what item, status, ypos, xpos.
Items:
0x00 crashes the game.
0x01 ?
0x02 Speed (S) -- Increases max speed from 784 to 896.
0x03 Time (T) -- Gives 10 extra sec of gas.
0x04 Nitro (N) -- Gives 4 nitros.
0x05 Tire (R) -- Allows better acceleration in sand.
0x06 Jet (J) (hidden) -- Lets you use nitros in air.
0x07 biker (hidden) -- Prevents you from losing items on fall (but doesn't work because devs messed up, it seems).
0x08 crashes the game.
0x09 crashes the game.
Status:
I think this address is really the amount of times this item can be collected.
If collected, this address depletes by 1 and you need to go to the next lap to collect it again.
