openMSX 0.5.2

Shortly after the release of blueMSX 2.3, the openMSX crew have released a new version of this popular emulator. As usual a new version of Catapult, the user-friendly GUI/launcher for openMSX, has been released as well. The most important changes in this new version of openMSX:

Improved timing on turbo R machines
Improved V9990 rendering
Added scaler: HQ2xLite
Updated Okazaki YM2413 (MSX-MUSIC) core
Fixed a bug in the SCC emulation, which screwed up some sound effects
Fixed MSX-AUDIO sample RAM access
Fixed the timer accuracy of OPL4 and MSX-AUDIO
Added a DirectSound driver for Windows, this should solve some of the problems Windows users have been reporting
Added sound logger: writes played sound to a WAV file
Added disk manipulator: commands to import/export files from disk images (experimental)
Added several debug commands
Extended IPS patch support
Added trainers.tcl: hundreds of game trainers
Added a cheat finder script: create your own game trainers
Updated C-BIOS to 0.21
New default console background and font
New openMSX icon

Please keep in mind this are just the highlights, you can read the release notes for more details on the changes in this new release. You can download openMSX 0.5.2 here. Source and Win32 installer packages are available now, Debian packages and Win32 ZIP will come soon.

The many changes in the new version of openMSX are likely to positively affect its EmuRank in the MSX Emulator Comparison. We'll try to update the Emulator Comparison as soon as possible, it will be interesting to find out whether or not blueMSX is capable of maintaining its lead in the MRC EmuRank Charts or that this new release puts openMSX back on top.

Rikusu : use Catapult AND my boosted machines (that require the roms used by the generic MSX1-2-2+ machines and the Turbo-R FS-A1GT in blueMSX).

It's really the easy way !

Rikusu: Explain your problem to us and we'll try to guide you through it.

@Mars: maybe I should try that

@mth: After installing the Windows version, copying the system ROMs in the indicated directory and booting the emulator, it still seems to be using C-Bios, which apparently only handles ROMs atm, and I don't see how to change any setting. The problem can probably be solved easily by reading the manual (duhh), but I just wanted to see if I could get this new version up and running without having to read any how-to's (had some problems with older versions as well which weren't solved as easily as through reading the manual ). But if you're able to tell me what to do...?

Rikusu - are you sure you're using catapult?

By Sama

Ambassador (2068)

19-06-2005, 16:33

I'm not - I don't know what Catapult looks like I downloaded and installed the newest full package, isn't Catapult automatically installed?

If you don't have changed the default settings of the installation, Catapult is installed and you have even a shortcut in the Windows general menu.

Rikusu: if you got a GUI to launch openMSX with, you're using Catapult. At the top left, you see the setting what MSX to use ("MSX type"). By default it indeed uses C-BIOS, to make it work out of the box. Choose a machine of which you installed the ROMs in the designated dir and press Start! (It's as easy as that...)

I can't believe you missed this thing, btw!

Manuel, you have 2 kinds of Win users : some prefer installers, some hate installers.

For this second category, it's not a problem to unzip correctly (with the subdirectories) the openMSX package in the directory that they have choosen (and eventually to create a shortcut to Catapult).

I just realized that openMSX does not compile out-of-the-box on Mac OS X 10.4, because the default compiler in OS X 10.4 is gcc 4.0 and openMSX seems to have some problems compiling with it. After changing the compiler in the openMSX build config to gcc 3.3 everything worked fine.

Hmmm... those line-interrupts does not work well yet... or at least what I do with them.
I guess I just have to wait for the next update before I can stop using the Dragon Engine

Line interrupts work perfectly. With pixel accuracy anyway, I don't run it any other way.

Can you elaborate on this please.
Maybe you are experiencing a known problem, or you have found a glitch in openMSX that we aren't aware of

By Manuel

turbor/Edwin: he's talking about the V9990 line interrupts. They are implemented, but not completely, if I understood Wouter correctly.

jr: it seems gcc 4.0.0 which is shipped with Tiger has some compatibility problems. openMSX 0.5.2 compiles fine on gcc 4.1 prerelease. There is more software known not to compile on 4.0.0... It's a bit of a shame they shipped it with Tiger... It's just a bit buggy still.

Oops! Sorry about that. I did mean V9990 line-interrupts, anyway the thing is i rewrite the scroll control
registers during display period and that part is not supported (yet).
A anoying feature the V9990 has with rewriting the Y-scroll control regs during display period is that the
high part is ignored. By example, before the display start you write 0 in the Y-regs then wait till displayline
128 and then write 260 in the Y-regs. Now what you expect (or what I did) is the display continueing form
line 260, but this is not the case. What happens is that the display continues form line 4. So forget about
a two-player-split-screen-sonic-game if the stage is higher than 3/2 screen (if you want 2 layers that is).
Anyway looking foreward for the next update.

maybe Catapult has some error, the extensions selections don't made any changes in the emulation behaviour. I opened an item on sourceforge bug tracker (1225491). Beside that fact, the emulator work's very well, and i like the new improvements.

Bug found and probably fixed. See the bug report.... it only affects builds that use wxGTK, because it's actually a bug in wxGTK

Manuel, thanks a lot for the fast bug-fixing.

BTW, i make a small portuguese "openMSX linux kick start with some screenshots", if someone is interested, go to

http://www.wpilon.org/emulacao/linux/openmsx.php

At this time, only portuguese version are finished.

In this site, i put the Slackware 10.1 packages for the SDL* wxGTK* and openMSX*, easy to install (download it && installpkg *.tgz), maybe this are useful for the Slackware Users, even if you don't speak portuguese.
