I'm lost. I'm do need to discover which file of the openMSX source is used by which interface (I'll list them afterwards).

http://openmsx.svn.sourceforge.net/viewvc/openmsx/openmsx/trunk/src/fdc/

Off course there are some very obvious ones, like MicrosolFDC and TurboRFDC.cc, but the comments don't help me to find the trail. I'm trying to discover the files used by the following WD2793-based disk interfaces to learn about the differences between those and the Microsol:

- Sony HBD-F1

• Philips NMS-8250 internal disk interface
• Sony HB-FXDJ internal disk interface

I tried looking at the XML files, then to search on the sourcecode. But there are very little comments describing how things work so outsiders can learn about it.

I'm asking for support and also humbly asking: pleas comment the code in a way an outsider can quickly figure out how the puzzle fits in.

Here's an updated version of the Acid1Test. It fixed the RAM layout problem reported here

It also adds some characteristics to catch buggy programs that fail to run in Victor HX-9x series and National FS-4x00 series. Se the built-in changelog for more details.

Hello,

When I type "set cmdtiming broken" on openmsx-0.5.0, it
does not work as it whould.

I took a look at the code and noticed VDPCmdEngine.hh
has a little mistake. This part of the code:

inline int getTiming() {
return brokenTiming ? 0 :
vdp->getAccessTiming();
}

Should in fact be like this:

inline int getTiming() {
return brokenTiming ? 4 :
vdp->getAccessTiming();
}

Best regards and congratulations for this excellent
emulator,
FRS

If I understood correctly, from v0.8.2 openMSX now supports MIDI output on Mac OS-X.

I tried the following command on the shell, but the MIDI still doesn't produce any sound:

plug msx-midi-out Virtual

Are any other commands/configuration required?

PS: It may be a good idea to update the manual with Windows and Mac examples:

fake joystick support: some games can only be
controlled by joystick, and if you don't have a
joystick on the PC, you still want to play the game.
So, the cursor keys of the native system will be
redirected to the openMSX joystick.

On the openMSXsource there's an input device called "joypad" that isn't described on the openMSX manual: https://sourceforge.net/p/openmsx/openmsx/ci/master/tree/src/input/JoyTap.cc

The idea is to have multiple screens on which the

as well. The effect of this would be the possibility of
playing games like salamander or f1-spirit over the

is doing from somewhere far away.

To make the throttle option throttle even more, it
would be nice to be able to turn off the VDP timing
(i.e. instant execution of VDP commands). This can
break some programs though, but for some applications
(I want it to do something fast!!) it is very useful.

Maybe "motion control" is a nice feature. You can use
it to force openMSX to run in slow motion (slower than
realtime) or fast-forward style (faster than realtime).
When a game is too hard, it really helps to play at 80%
or 90% of the actual speed. I played Space Manbow a lot
when it was running too slow, but as a result I can
also play it better at realtime. Practicing at realtime
is frustrating because each time you die you are put
back a while without decent weaponry.

Implementing motion control would be easy: in the
realtime sync, the target moment in real time as adjusted.

THUS: a bit more subtle than throttle mode.

Here's a small patch that let's romdb.xml be searched

Now the romdb.xml needs to be in the current directory,
otherwise openMSX won't start. This patch fixes this.
(patch MSXRomType.cc < romdb.patch)

It's not very impressive, I know, but it is nice to
test this patch tracker. For now I let the mail of this
tracker go to the devel list. If you want me to change
this, please let me know.

Hi all!

The register 19h of the Y8950 currently returns 255 by
default, since it's not implemented. But the sane value
to return would be 0 (zero), since by returning 255 you
activate, at boot, the built-in music editor (aka
Synthe) of the Panasonic FS-CA1, which is not desirable
at all, since this prevents this MSX-Audio to be used
in games and BASIC. This pratically turns it unusable.

Yes, I know about holding the ESC key on boot, but I
also know this also disable the MSX-Audio BIOS, thus
also preventing the CA1 to be used in games and BASIC.

Please note that the (IMHO, crapy) music-editor can be
activated later on basic by typing "CALL SYNTHE".

The fix is easy. In Y8950.cc, line 1126, there is:

case 0x19: // I/O DATA TODO
default:
result = 255;

It should be:

case 0x19: // I/O DATA TODO
result = 0;
default:
result = 255;

After fixing this bug, there's 2 easy tests to verify
if everything is working well:

1. Boot the openmsx, and run any Compile DiskStation.
   The music should be played by the MSX-Audio Instead of
   the MSX-Music. It will sound a bit diferent from what
   you are used to hear. You can also test Xevious,
   Golvellius-2 and almost all Compile games. Aleste-2 and
   RuneMaster-3 have bugs in the MSX-Audio support, so
   dont worry about them.

2. Find some music written in BASIC for the MSX-Music,
   like those published by MSX-Magazine. To play them on
   the MSX-Audio all you need is to change the CALL MUSIC
   for CALL AUDIO. The parameters are the same.
   This happens because the MSX-Music BIOS is a stripped
   down version of the MSX-Audio BIOS. But in the
   MSX-Audio is possible to redefine any instrument and
   there's also many commands for ADPCM playing/recording
   in BASIC.

Best regards to the openmsx team,
FRS

At the moment one can only put a disk image in drive B
via the XML or via the commandline as follows (please
check if this is the only way):
openmsx config.xml drivea.dsk driveb.dsk

There is no way to put something in drive B from the
Console, which is very annoying if you're working with
more disk images at the same time. Please do something
about it! :-)

This is a mix between the set1 and set2, intended for debugging.

1. Uses icons from set2
2. Displaced horizontally as set1
3. It's arranged in a way it stays only over the MSX border and never over the main image
4. It's always on (icons don't fade out), which is better for debugging

I hope you like it.
