To install LEPIX you first need to compile the sources. LEPIX is written using MADS assembler by Tomasz 'TeBe' Biela, available on the LEPIX homepage. To compile issue the following command: mads.exe lepix.asx /o:lepix.xex /l /t /m:xasm_macro.asm This will create LEPIX.XEX file. Note, that since LEPIX supports multiple graphics modes it is necessary to tell it which mode to use for the current compilation. The used module is defined in lepix.asx file, in this part: icl 'mod_mic.asx' ; icl 'mod_inp.asx' ; icl 'mod_cin.asx' ; icl 'mod_hip.asx' This code means that MIC version will be compiled. If you need to e.g. compile INP version, just modify that code into: ; icl 'mod_mic.asx' icl 'mod_inp.asx' ; icl 'mod_cin.asx' ; icl 'mod_hip.asx'
