Hi!!! Well 've been for so long out of the forum and i've been studying, but i've found a so interesting project SWAM http://www.s1mp3.org, it has just started, so it's in designing phase. This project wanna make an OS for the MP3 Players knows as S1MP3, a picture here:

also here you can see other models http://www.s1mp3.org/wiki/index.php/S1mp3_types

As i use FASM for all my projects, it will wonderful if we add Z80 Instruction set to FASM, as it has ARM support, well at least it's on project, but the Z80 support will be easier no?.

Well I'm working on it and as they need ASM coders, so here we're, let's work on it.
Any question here or in the forum http://forum.s1mp3.org/

as this is mainly question about adding Z80 support and point to dead project, i move it to internals section.

anyway, this is interesting - how far is FASM modularity? would it be problem to add Z80 support (besides lengthy adding assembling itself). I mean something like FASMARM did....

Anything new since 2006 for Z80 support ? Rolling Eyes
Maybe any documentation how to change register/instruction set ?

I found some documentation about "The official guide to flat assembler internals" (fasmguide.txt) at page 7 in forum "compiler internals".
Have 6 more pages in this sub forum. Confused

http://board.flatassembler.net/topic.php?t=3883

This is from 2005 - so I hope it will give at least some information but I think there was changed many in the years.
So I hope I could work with this and step through the code.

Any hints or links to more documentation is welcome. Smile

Please dont support licensed algorithms!

A quote from the WiKi...
In September 1998, the Fraunhofer Institute sent a letter to several developers of MP3 software stating that a license was required to "distribute and/or sell decoders and/or encoders". The letter claimed that unlicensed products "infringe the patent rights of Fraunhofer and Thomson. To make, sell and/or distribute products using the [MPEG Layer-3] standard and thus our patents, you need to obtain a license under these patents from us.

When you read my posting I was not asking for MP3 support, only for Z80 support.
This was an old thread from 2006 but one of about five with Z80 requests.

Anyway today the world is using AAC, MP4 and other different file/compression formats.
Who cares about Fraunhofer ? Rolling Eyes

And here I thought AAC was a proprietary crApple format, until I looked it up on wikipedia... which makes it sound like AAC is better in every way compared to MP3?

*sigh*, and I just transcoded 16GB worth of MP3s from FLAC for my portable player.

I think so. Unfortunately my 4 year old SONY MP3 player doesn't support it. Confused

Move into Non-x86 architectures Smile

Both MP3 and AAC are proprietary. AAC is reportedly technically superior to MP3.

+ inifinity Use FLAC or Vorbis for audio Wink

I read all documents in this area.
There are not too much themes there, they do not fill a full page. Shocked

What's the difference between "AAC" and "MP4" ? Shocked

And say "portable audio player" instead of "MP5 player" ... and when buying such a thing next time, check for Vorbis and FLAC support.
