Hello

I know some one made a hardware version of a Mp3 player for MSX

Is it possible to make a software MP3 for Turbo-r ?

It have the sample hardware, but maybe its not good enought.

If the player are made in pure assembler, it should be possible ?

There is a MODplayer for Turbo-R. But ofcause if you only make the Software version, only Mono.

Should the Turbo-r be powerfull enough, to play mp3s using moonsound?

-Claus.

iirc it took a Pentium60 to playback a stereo 128kbps MP3 back then. My 486DX2/66 could only playback 128kbps in mono iirc. So, if you think a tR is as powerful as a P60, then it's probably possible for 128kbps stereo mp3's.. Hannibal

hehe Smile

I dont know if it was possible or not.

Sometimes PC hardware is not as smart as msx hardware Smile

And maybe some really smart programming Smile

I dont know, but i know the modplayer worked, but its not the same.

Iirc the tR is from 1991, that's 16 years ago. You can expect today's chips to be smaller, smarter and faster. My cellphone from 2003/2004-some has 32768 colors (like g9k), and more FM channels than my Moonsound. So, yes, while the tR might still be the most advanced MSX, it's still 16 years old and thus outdated from today's hardware point of view.

A pocket MP3 player has a specialised chip, which can't do anything else than only decoding MP3 data Wink It can't be compared to an all-purpose CPU like the R800. The requirements for a MOD player are a lot smaller, as you only have to scale up/down some sample data and mix (add) them - nearly no math, it's not much more than just a small stupid byte read/write loop.
But the JPEG viewer for the MSX is even very slow on the R800, and this is something which you can compare with decoding MP3 data.
So I am sorry, but it should be impossible to play MP3s on the tR even with super optimized asm-code... Smile2

Jpg used in web are usually small, perhaps is not a great problem to decode it.

Why not png? seems more suitable for MSX if you ask me. No color errors an MSX can't display.
