What hardware extension for MSX would you produce if money were not an issue?

As soon as you add modern-day stuff like USB, Ethernet etc you soon have things that can be used by 1 or 2 dedicated softwares at best. Build mini-micro webserver using ethernet port? There's better hardware for that purpose. Make controller to change an old oven into DIY reflow solder oven? There's better hardware for that purpose. And so on.

Start with software, and then you get: new box that runs most (all?) of existing MSX software. And maybe software for other systems too if hardware allows it. For this purpose there exists hardware that's cheaper & better than what you could possibly create yourself.

Therefore I'd go for a 'systems integrator'. Some party that selects hardware (say, an existing FPGA development board), puts into nice case, adds MSX connectors needed, prepares flash cards, makes licensing deals so that much software can be included in starter package, includes decent manual for MSX newbies, and so on. So that you get a one-stop-shop to buy replacement box that runs your beloved MSX software. Or allows a quickstart for someone that's never heard of MSX and prefers box-hooked-up-to-TV over emulators...

BTW, 2 ideas:
1) I always asked openMSX guys to start implementing new features on the emulator. MSX extensions would cost LOTSAMANI in real HW, but just a few academic effort to be emulated.

2) This was my original idea that somehow was transformed into Franky MSX extension:
* Get a MegaDrive
* Port MSX basic to it and add a few SW extensions to use the new features like screen modes and audio stuff (let's call it MD Basic)
* Create a cartridge with MD Basic on it + USB connector (or ps/2) to connect a keyboard (mouse maybe) + an SD disk drive.

...and... let the developers do the rest.
1st program to be created: Execrom
"execrom sonic.rom"

MSX3 would be created with tons of games...

Maby a idea for sound freaks

VS1063 - MP3 / OGG / AAC / WMA / FLAC / G.711 / G.722 Audio Codec
•Encodes a multitude of audio formats, all at 8-48 kHz, mono and stereo:
•MP3: All samplerates and bitrates of MPEG 1.0, 2.0 and 2.5
•Ogg Vorbis
•16-bit PCM
•G.711 u-law and A-law
•G.722 ADPCM
•Decodes multiple formats upto 48 kHz:

•MP3 = MPEG 1 & 2 audio layer III (CBR+VBR+ABR)
•MP2 = MPEG 1 & 2 audio layer II optional
•Ogg Vorbis
•MPEG4 / 2 AAC-LC(+PNS), HE-AAC v2 (Level 3) (SBR + PS)•WMA4.0/4.1/7/8/9 all profiles (5-384 kbps)
•FLAC lossless audio (upto 24 bits)
•WAV: 16-bit PCM, IMA ADPCM, G.711 u-law and A-law, G.722 ADPCM
•A new full-duplex codec mode allows both input and output using many formats:
•16-bit PCM
•G.711 u-law and A-law
•G.722 ADPCM
•Streaming support
•Upto 96 KiB RAM for user code and data
•Unique ID for code protection
•I2S interface for external DAC
•High-quality stereo A/D converter
•Serial control and data interfaces
•Can be used either as a slave co-processor or as a standalone processor
•UART for debugging purposes
•New functions may be added with software and 12 GPIO pins
•EarSpeaker Spatial Processing
•Bass and treble controls
•5-channel equalizer
•Low-power operation
•High-quality on-chip stereo DAC with no phase error between channels
•Zero-cross detection for smooth volume change
•Stereo earphone driver capable of driving a 30­-ohm load
•Quiet power-on and power-off
•Separate voltages for analog, digital, I/O
•SPI flash boot for special applications
•Hardware drop-in replacement for VS1053 (control software still needs to be modified)

Thanks a lot for the info! Those models are probably a bit harder to obtain..but, hey, let's start with the MT-32 and go from there..Hannibal

I got a spare sc155 (I used it before i got my sc88) module that i'm willing to sell, just send me a e-mail if you are interested.

Yeah. Another cool idea: we could clone Kojima and use some kind of conditioning to make him an unconditional MSX fan, so that all his new productions would be released for MSX only. Metal Gear XXI - MSX2 MegaROM SCC LOL!

@pitpan: One or two more Metal Gear games for MSX would be highly awesome. But 100+ more games and it would end up being boring, as it happens now with the PS. Smile

my 2 cents:

Build a supercartridge. Some existing carts are really cool, but not everyone has them, or has enough slots to use them all (at) the (same) time.
Some HW is very local: Japan only, Brazil only, Holland only or Spain only. It should be cool if all msx-ers would have the same expansions/ functionality. And that makes that some software will have only very limited numbers of possible users/buyers...

What this supercart could have:
-multiple soundchips (stereo),
-some connectivity (RS232/ethernet/usb(mass-storage))

so no hassle with switching carts/tapes/disks or big slotexpanders, but more msx-ers with the same expansions/possibilities.

Since then, this is sort of what happened...
