ROM Hack Boxboy level editing

[gamesquest1]

finished box boy so i decided to have a look at its level format and it *seems* to be pretty simple stuff, not looked too much into it, and not being a programmer i was wondering if anyone had looked at it, managed to make some pretty simple edits manually, like changing spikes for normal conveyor belts or removing them completely, you can also change the number of blocks you can make, max seems to be around 25, if you go crazy and set it to like 100 the game will just crash opening the level, but for anyone interested the levels use LZ11 compression and if you want to change the number of boxes you can make on the level you can either edit the compressed level at 0x2A to whatever number you want, or if the level is uncompressed its at 0x2C

in regards to the level design editing i haven't really looked too much into it but these are a few of the values i found, some of the *nothing*'s or "blank tiles" might actually be something but require something else for it to work, but it seems to have different layers...as i said i only had a quick mess about manually editing stuff, but if it helps anyone else here is stuff i tested

I was thinking about this too, got distracted before I got any further than decompressing a level tho. Good work poking around, hope it will inspire me to have another look. It would be nice to end up with a full level editor, but I guess that's a way off.

Yeah the level layout seems pretty simple and tbh the game is fairly simple in design so I doubt a fully featured level editor would be that far fetched......just depends if anyone with the programming ability takes a look

I thought about trying this but then I was paying more attention to more exciting thing because here i'd have to test and test and test...
Btw. Do you still offer "Hardmod-Service"? If yes, are you free atm?
