hwrd Posted February 7, 2020 Share Posted February 7, 2020 I am stuck on level 141 in Lode Runner on the 64, and am wondering if anyone knows if the keys can be redefined? (the U and O keys for digging are too close to the direction keys for me to use well.) All I found remotely resembling useful was https://entropymine.com/jason/lr/misc/controls.html, but I could not get this to work on a C=64. (tried a THE64, and a real C=128) Thanks in advance!

digdugnate Posted February 7, 2020 Share Posted February 7, 2020 i don't believe the keys can be redefined. here's a link to the manual: https://archive.org/details/Lode_Runner_1983_Broderbund_Cartridge/mode/2up Quote Link to comment Share on other sites More sharing options...
hwrd Posted February 8, 2020 Author Share Posted February 8, 2020 Thanks. Looks like I will have to get used to one hand Lode Runner. ? Quote Link to comment Share on other sites More sharing options...
carlsson Posted February 8, 2020 Share Posted February 8, 2020 (edited) Ok, I found that the key controls are hard coded starting at $9A99, give or take. It is possible to modify the CRT file with the controls of your liking. You could try it in the emulator first. Enable the monitor (Alt + M) and type in the commands: A 9AAF CMP #$3E [return twice] A 9AB9 CMP #$11 [return twice] X to return to the game It will temporarily reconfigure digging left to Q and digging right to R. This BASIC program will display decimal values for each keypress, if you want to figure out other keys: 10 PRINT PEEK(197):GOTO 10 It displays 64 when no key is pressed. Write down the keys/values you prefer, which then can be converted to hexadecimal. The CRT file probably needs to be modified in a hex editor and saved. Not sure how you load it on real hardware, except extracting the PRG portion of it and soft loading from e.g. disk. I can help you with the fine details once you've settled how you want it to be modified. Edited February 8, 2020 by carlsson 1 Quote Link to comment Share on other sites More sharing options...
