MSX asociation what kind of patents has?

The ROMS? and nothing more?

The msx slotting/subslotting?

The VDP or PSG structure or framework?

i mean, if somebody do a MSX hardware without the ROMS... is ilegal?

Emulation is still a grey area.
For example, emulation of FM soundchips might violate patents on FM technology. Also, system architecture might be covered by copyright.

There is not enough jurisprudence to declare emulation of computer systems legal or illegal yet.

Is this not similar to the so called b-clones in the pc world, in that case,I think it's allowed.

If you create a new hardware, which is compatible with the MSX system, and doesnt use reverse engineering to do it (and of course, dont use the system Roms) then *I think* it is perfectly legal.

The catch is how to do something 100% compatible without reverse engineering the original...

Also, system architecture might be covered by copyright.Actually, that's covered by patent law entirely. Had the MSX system been patent-able at all, which it couldn't have been as it was based entirely on existing technology, it would have expired anyways... Apart from that, most hardware isn't covered by patents at all. It's just often not viable to patent things anymore. The most you'll see nowadays (except ofcourse the really big companies) is pending patents. By the time the patent would actually come through the technology is obsolete anyways...

but i want to know if, we do a MSX standard, emulating chips in FPGA it is diferent legally than to unsing the real chips? in a new msx mobo?

And what exactly was patented by the MSX asociation..

eMSX++ will be ilegal because it has or has emulated the msx architectured?

if we do a v9958 with compatible framework... in FPGA, it is ilegal? We need yamahaa licences? .... Just think that for do that we can't use the original chip design because is unavailable, so is needed to do a chip matrix from zero.

the same for PSG , the PPI is general purpose, not problem with that, so, not problem because the slooting indeed i think is unpatent-able..

the Z80 from zilog, if we do a z80 in FPGA??? is legal... IF not, how are NISHI planning to do one chip MSX.. got zilog licenses?

This is yet another one of your bullshit posts I've been laughing my head off about.

If MSX was existing technology, why do most of the MSX chips have (c) ASCII Corp. on them?
ASCII helped design most of the chips (V9938, R800, Y8950, the MSX-ENGINE's etc).

Existing technology would be true for MSX1, but definitely not for MSX2 and up.

In most countries reverse engineering is still legal.

can be patented the way to connect a general purpose chip like the PPI ?

remember the PPI 255 was a chip older and a lot of olds computers got that.

i aren't talking about the s1985 or s1990 when i talk about msx engine...
