Some days ago I promised that I'll make such example. And I even did it, partially. But for now I must work for some another projects first, and it's take some time. So, I decide to show current version of code to community, mainly because it contain ROM-version of PT3 player, which can be useful for somebody.

Archive contains all current source code + resources (music and sfx bank) to compile with sjasm, and already compiled example (in form of 16K ROM, MSX1).

Thanks Shiru.

But watch out. I made the same mistake in the first port of the PT3 replayer for MSX. The 7th and 6th bit of the 7th register of the AY-3-8910 must be %10xxxxxx.

Just do something like:

CH_EXIT:
LD HL,AYREGS+AR_Mixer
OR (HL)
RRCA
OR %10000000
AND %10111111

It is very important. Otherwise you can broke the original hardware.!

Thanks Shiru.

Great work. A ROM replayer is indeed something we can use.

Thanks.

Actually, the only problem detected 'till today is just that the joystick in MSX2+ doesn't work. Nothing else ...

It can blow up (short-circuit) an MSX with a real PSG (not in MSX-ENGINE). You should never do this, really. openMSX 0.6.2 warns you if you do it.

My Sony HB-G900P has also not an MSX-ENGINE, and doing this could hang it in such way that it needed power off to restore. Luckily it wasn't fried!

Shiru, I'd love to have a look at this. Is there any way you could upload to someplace other than rapidshare? Rapidshare is a poor service -- it disqualifies many people like myself from free downloads.

dioniso, yes, I remember about it. But is there problem in sfx player (I just don't check, this part was changed by AlCo)? Look:

	ld a,7
	out (#a0),a
	in a,(#a2) ;we read value from R7
	xor e ;then set/reset TN flags
	and d
	xor e
	ld c,iyh
	out (c),a	;and put value back in R7

ro, here is my editor: http://trd.speccy.cz/pcutilz/AYFX04.ZIP

It seems the code doesn't take into account these two bits ... just do the patch again before sending the new Tone and Noise bits to R#7.

	ld a,7
	out (#a0),a
	in a,(#a2) ;we read value from R7
	xor e ;then set/reset TN flags
	and d
	xor e
	ld c,iyh
	or %10000000
	and %10111111
	out (c),a	;and put value back in R7
