This tool lets you insert level, overworld, game mode, status bar, sprite and global ASM without using a patch. See the read me for more details.
Updated Asar to 1.71.
Fixed newer Asar printing weird path-related warnings.
Fixed a crash when stdin is either redirected or set to empty.
Fixed a crash when an .asm file prints either an empty or white-space only string.
Moved working .asm files to the dedicated ./asm/work instead of ./asm/.
1.3 changes: updated to use Asar 1.61. It should be possible to use the Asar 1.50 dll too if you need for some reason.
Yeah that's so weird to insert 2 ASMs in a level. The tool is so simple that I always imagined it would insert them both if I just both 2 lines with the same level number.
I mean, once you know, it's not really hard. But weird.
