Okay, now I come to think of it, I admit it will also be very useful to
display 3D rendered stuff. Okay, leave it in, it's a good idea.
Yes! (-; No only 3D... videos also.
Okay, I'm sold!
It will not matter much for games, but things like 3D and video will have
great advantage of this.
BTW, use LDI e OTI are usually better, when working on video, than
OTIR and LDIR... But remember: OTIR is the same speed as LDIR *inside*
de Z80. And on MSX, every OUT, specially for VDP, receives some Waits...
and so, on MSX OTIR to VDP is slower than LDIR to VDP.
I made a mistake as
By the way, an idea just popped into my mind...
For the Z180 CPU, eventually also an 'emulation' TSR could be made, which
emulates the Z380 through 'trapping' of illegal opcodes. It will be
_really_
slow though...
But it'll not "that hard" to do... But it'll only works if the Z380

Hi,
I have a (small) coding question, probably not so difficult. But I'm still
learning.
I have the following subroutine:
ld hl,(table) ; load table into hl
inc hl ; increase table
inc hl ; increase table
ld a,(hl) ; put value in a
sla a ; *2
sla a
ld (hl),a is a valid instruction (01110111b)
so I guess its a logical error

Hee, sander...
Just look at the scroll we made last summer!... The updating of the sprites
(the stars which move) also uses the ld (hl),a command... hehe.. just look
for the 'IncSprite:' label somewhere in the middle of the code...
hehehe...

A little while ago I have mailed about an external floppydrive connector
that was on my second hand Turbo-R.
Somebody would like to help me if I profided the pin assignments where the
external 15pin female D connector was connected to. Now I have opened the
Turbo-R I wrote down the pin numbers.
Besides, I don't even know you CAN read S#2 in BASIC
since the interrupt routine always expects S#0!
You can, A=VDP(-2) will do the job.
Doh! hehehe, forgot about that one ^^;

It would be nice if the BIOS could be in FlashROM. That way, the BIOS can be

Hello to everybody.
I will tell some things about Z380 in a fast way.
1- As I own one Z380 card, I know what I am talking about.
2- About a FlashRom for Z380 BIOS: It is dangerous !! If you program the
BIOS and make a bug, maybe the Z380 will never run again because

Status: unfinished
The I/O is a bit tricky. This is what I understood from the Z380 specs, but
I'll need verification. The problem is not that the MSX I/O can't be used.
The problem is if the extended I/O range can be used. As far as I get it
now, if you output for example a

It is like PC FlashRom Bios trouble, and famous VIRUSES. The
I see only one option to extend the I/O address range. B1 shouldn't be

In the same way as ADVRAM works, but doing a "bridge" over Z180.
Hmmm... How will the registers be read then???

I just released the brmsx 2.5.
Main new features: support to 7MHz clock, ADVRAM and VDP fixes.
http://www.lsi.usp.br/~ricardo/brmsx.htm
Also finished the ADVRAM page.
This page includes detailed description of the standard,
sample programs and benchmarks.

Yes, it easily can if you have an IDE version #4.1 interface because
that one has a socket for the flashrom. Flashrom types that can be used:
AM29F010 (128kB) and AM29F040 (512kB);

Those are the same as the Z80 versions, but work different in another mode

What I've tried to say (but I think I had failed) that is:

No they do not. In this case MSX2+ means, this program works on
MSX2+ Computers with at least 64k RAM.
