To start, I am new to assembly. I would like to know if there is any way to compile ASM files without using Doors or PlusShell. I know that I can use the compiler in PlusShell, but I don't want to necessarily use PlusShell on my 89. Two such ASM progs that have been made for the 89 and don't require any shell are Tetris 89 v0.60 and Nibbles-89! v1.1.0. Thanks in advance for any info possible.
