Planning on using the VMU as a display for an analog sensor. I have all
the hardware,
and am hoping to get started now that snow season is approaching.

Planning to re-write the drivers for Linux 2.4 for 2.6 at some point...

Hey there!

Is there anyone left developing or planning to develope anything for
the VMU?
I would like to ask/share some specifics about usable programming
languages.
Till now I am using assembler, but maybe there is someone out there who
can tell me about his experiences with alternative languages.

Hi,

first i must say i'm glad to see this list is active again, and some
people that made excellent things in the past are still around here :)

I'm working on a port of softVMS for the DC using KOS. I successfully
ported Marcus Comstedt's original source, but there is a bug with some
games. Indeed, with games like Powerstone the xram isn't filled
properly from the 8th row from the bottom.

I found Alessandro Sanasi's version which fixes this bug, but sadly i
couldn't find the corresponding source code anywhere :(

So does anyone know of this bug, what's causing it and how to fix it?
Or if you know where to find Tyro's source that would help as well.

Thanks in advance.

But first, thanks to the people who had a copy of my
.zip file.

Today I learned...

If you enable p3int, the VMU wakes up faster from
sleep.
...
If you enable p3int and don't process it, button
response is
not good.
...
The firmware sleep routine enables p3int.

mcr and vccr can be turned off with bit instructions,
but
want mov instructions to turn back on.

In a very quiet room, if you hold it to your ear, you
can
hear a sleeping VMU ticking.  If you hold down a key,
it
will buzz.

Things would be a lot easier for me if Sega had
released
complete specs for the VMU - especially for all the
SFRs.
The websites I can find with info don't match up in
many
places.  The source code I have found is at best, less
than
optimal - likely due to inadequate information.

MY VMUs clock at 6.051MHz, 870KHz, and 32.2KHz -
The emulators clock at 3.6MHz, 3.6MHz, and 19.6KHz.

Does anyone know....

If you can use P1 like a parallel port?
If you can set VSEL for auto-decrement?
Any fun hardware things to do with a VMU?

Harry

     Does anyone have a copy of the attachment?  I lost the .html

Planetweb 3.0 supports Java, but it was a commercial product, Planetweb
sold it for $20 less than 2 years ago.

You can still find it on Ebay, although I dont reccomend it. It's
horrible. I bought it because I have a BBA, and that's the only version
which supports it, and you can't go to more that 5 or so pages before
the whole browser locks up. Java support isn't that great. Less than
half of the applets you try actually end up working, the rest run out of
memory, or crash the DC.

hi,

To my knowledge non of the Sega dreamcast browsers have java support,
how ever they do have Javascript support.

I learned this the hard way http://www.jumpstation.co.uk/jvmu/

If you want to run a 'real' java app on the dreamcast I would recomend
using linux on the dreamcast.

Of course it all depends on what you actualy want to do.

What do you want to use Java on the dreamcast for ?
Networking, graphics, games ??

Wow!

     You have a wealth of useful information on your
website.
I have changed my code... it used to toggle between
600K for
computing and 32K for wait loops.  Now I go from 6M to
32K.
On many websites, it states the LCD hardware requires
600K
for updates.  I made a typo and it showed that you can
update
at any clock speed, but 32K is noticably slow.

     The more useful (to me) of your programs is
rc-clk.s.  I just
have to figure out how to create a 0.05 second
interrupt then
I can halt the cpu instead of doing delay loops.

Thanks some more,
     Harry

A long time ago when I wrote Alienfighter I solved this problem by doing
a speed calibration at the start of the program. That way I somehow got
a stable framerate in RC clock mode. Don't ask me about details, too much
time has passed, but you can still get the source code at my homepage

I haven't done any VM programming since a while, but there's
definitively an high-res timer available. Check the available
public docs.

What you may be experiencing (and what I also experienced) is
that done of the available free emulator support timing/HALT
properly.

I have released 4 games and all of them were properly timed
but are running too fast on emulators, while they're running
good on a Visual Memory.

Hi,

     Is there an easy way to get a fast stable timer?
Right now I time everything in my games on the
1/2 second timer.  I do all computing at high
speed and drop it to slow speed for busy-wait loops
to save a little power.  I tried using HALT, but the
1/2 second response is too slow.

     On other systems (Lynx, NGPC), I do busy wait
off the vertical refresh clock, but I don't see
access to that on a VMU.

     A timer with say 1/10th second resolution would
also allow my game speedup progression to be more
gentle.  It is rather abrupt going from 1 second delay
to 1/2 second between waves.

Harry

Hi,

     You need:
1) A VMU emulator and/or a way to get your
    program to a real VMU.
2) A VMU assembler.
3) Optionally, VMUscript for a slightly higher level
    programming language.
4) Example source code.

All the software is available at no cost from the
'net.
If you can connect to the 'net from your Dreamcast,
there are even ways of getting your game onto a VMU
for
no additional cost.

Hi,

     Here is the latest version of my VMU demo.
Use up/down to select between the different modules -
A to start, B to exit.  It's a bit incomplete now
since VMUscript crashes when I add anything else to
the source.  When I get done converting VMUscript to
C, I'll be able to add more features (like sound and
timezone settings) to the demos.

Hi again,

     I compiled it with DJGPP v2.02 and for some reason
it doesn't like a label as the first line of an

something strange in the compiler.  Any thoughts on
this?

     I also added 1 to the error line reported since
most editors start numbering from 1, not 0.

As far as I know VMUASM is just the normal aslc86k from Marcus Comstedt
compiled for DOS. Version 1.9 of this has some problems if you use macros.

The sourcecode for aslc86k can be downloaded at Marcus website at

most times it doesn't.  It is getting annoying.  You would think in

     Is there a VMU assembler available for Solaris or MacOS anywhere?

Harry

Hi,

     I downloaded the source Jul 6th, 2004 and am working on
converting it to C.  Why, you may ask...

1) It runs really slow compared to the VMU assembler
2) There are several annoyances in it
3) VMU Assembly code is tedious
4) Because I can
5) I'm working on a VMU game too
