My point is, if you start using too much external CPU power (many times more than a Z80 and something that wasn't possible to do in the 80's, the system becomes quite ridiculous. Then its not the same as a V9938. G9k is imo as you know from other posts close to the limit to what can count as MSXing.

But it all depends on how you look at it. The russians have done quite remarkable improvements with the speccy, but those speeded up speccys with several MB ram is really not something retro. And for me MSX is retro. Its like old cars. Of course it could be fun to rebuild it, but calling a new BMW with an exhaust pipe from an old beetle retro doesn't make much sense.

A bit out of topic maybe....

A co-processor is not the problem. The only problem for me is having a completely separated hardware which is only sometimes controlled by our old 8bit machines via play/pause commands. For me that's not so exciting. But ok, the "ipod" issue was only the third argument against onboard MB-sized buffer-memory Smile

Is the Moonsound ridiculous (it would've been space-age in the 80's!) ? Or is it only ridiculous with some decent SRAM (RAM was space-age in the 80's)? And what about SymbOS? Isn't it ridiculous to port "Windows9x" to an 8bit-system? (not so much concerning whether it can be done, but whether it should be done, from a retro point of view. A real retro-geek doesn't need a Win'esque GUI/OS, as he types "Run"cas:" all the way)

When is something ridiculous, and when is it not? And: whould you've said the same 12 years ago?

Is it ridiculous to plug a $900 videocard into a $300 PC just to play the latest games at 1600x1200? Should one say: "in such a cheap PC, there should only be a cheap videocard, otherwise get a faster PC" ?

One of the things that defined the MSX for me was that there were all kinda expansions one could gradually buy. Why not simply see an mp3-player -with its own RAM- as such an expansion?

offtopic it may be, but not less interesting Murdoch

ok, esp. for you Tongue

- big delays before playing an MP3

define 'big' .. I think we could bear some..

- additional costs

like? I dunno what hardware costs and such, but what would, say, 8MB cost?

Is this VS1011 doable as not-so-heavy addition for the OCM?

Here the same question.

Was mich schon lange interessiert, ist mit was für einem Aufwand wäre es möglich eine eigenen MP3 Decoder in einem FPGA, bzw PLD zu programmieren. Was wäre geeigneter PLD, oder FPGA (kenne leider den Unterschied nicht)? Wäre sicherlich eine schöne VHDL Übung.

Here an answer.

Vergiss es.
Schon das Programmieren eines DSP (Der MAS ist z.B. auch nur ein DSP mit festem Programm) ist schon schwer genug. Und dann willst Du Dir erst noch einen DSP selbst bauen?

Is the Moonsound ridiculous
No, because the Moonsound isn't 50x faster or better than MSX-audio. Its better, but within the limits Wink

whould you've said the same 12 years ago?
Not sure. If I was able to get something much faster or better to a competitive price I would probably like it. I think thats sortof what drives the speccy scene in that direction.

Actually that is close to ridiculous but if fast 3d is the only thing you need I guess its good.

I kindof agree, but to me its more about doing the best you can from an old system, whether its music, gfx, demos, or multitasking os'es. I've been tempted to port or implement a realtime os to MSX myself (I've been working with developing small OSes for many years).

It is indeed interesting. And MSX means different things to different people. No thoughts or feelings about it is wrong.

@Wolf: That's really an interesting discussion Smile It's not easy to define the limits. As an example IMHO the SuperCPU for the C64 is crap, as it replaces the complete system core and uses the remaining hardware only as a terminal - there is nothing interesting with it at all, as it is a complete different computer now. It's like having an Amiga with bad graphics - so why should I have a C64 with a SuperCPU?
Regarding SymbOS: The goal was to be able to run it on original 1985 hardware without any extensions, and so it's still retro somehow IMHO Wink
Anyway I have nothing against additional ram and any other cool add-ons. Regarding your comparison with the GFX9000: This card does NOT have any additional internal memory for storing and playing movies without the need of MSX CPU power Tongue

An usual 3MB MP3 would need about 30seconds or so I guess. For playing MP3 from a playlist this won't be so nice.

Short translation:
Q: Is it possible to develop an MP3 encoder in FPGA/PLD? What would be better, PLD/FPGA (don't know the difference)?
A: Just forget it, too difficult...

Anybody wanting for "MSX cotrolled iPOD" or MP3 player with own RAM I suggest using regular CD-drive. It is cheap to get, it is standard solution, you get same result, you don't need to do PC/Mac/Other -> MSX -> player memory and you get even better sound quality than with MP3. (BTW this idea was already used in Knightmare Gold.)

If we talk about MP3 sound card I very much like these current plans.
