Simple RLE Decompressor - LCD - 04-29-2011 Maybe not a bad idea: a decompress function for RLE encoded binaries (starting with dbyte contains length of compressed and a flag byte). Maybe something like UnRLE(sourceaddress,destinationaddress) returning the length of decompressed bytes or alternative, if the starting bytes are missing: UnRLE(sourceaddress,destinationaddress,length,flagbyte), or even with bank switching management. This will allow to pack more graphical and level-data into our programs. Maybe a job for britlion, to write a fastcall routine? This can be used for all Z80 computers then. Re: Simple RLE Decompressor - boriel - 04-30-2011 It's already done at speccy.org (a Spanish ZX Spectrum forum), and freely redistributable. I could include it as <rled.bas> or the like? I think some users here (e.g. apenao) have already been using it with ZX BASIC :wink: (not sure). Re: Simple RLE Decompressor - LCD - 04-30-2011 Sounds good. Speccy.org looks like a nice forum (also with the QL subforum), but I cannot find a search-function (maybe because I'm not a registred user) to find this decompressor. Any link please? Including it would be excellent.
