- more stuff by unknownfile at 3:18 PM EDT on April 5, 2010
- i have the executable format decoded for the most part thanks to a bit of reverse engineering, now what i need to do is emulate bus errors.
as you know, some x68k games use midi. to check to see if midi devices are present, the x68k does a check and waits to see if the check succeeds or a bus error is raised. the m68k core that runs in mame (as well as m1) does not support bus error emulation, so accesses to the midi ports cause the program to hang.
shouldn't be too hard to do now that i've got stuff figured out.

- thank you so much for this correction :), now the neogeo volumes sounds correct.
It is funny that This correction was made even before I wanted to notice you in the irc about that XD.
Unfortunenately now it seems that it does not support a few of my romsets anymore that worked with the old version, it gives some error message:
D:\1gJoNaI\PORTABLE\m1078a10-w32\m1078a10>m1.exe kof2001

thank you anyway.

- I get ROM load error's with Mortal Kombat 3, when with the original version of M1 it worked fine. (Other than the music sound strangely different...)

- later NeoGeo games use encrypted sound roms which you need to decrypt yourself. i'm thinking of having M1 decrypt everything so you don't need to worry about it.
also i don't know about the MK3 errors. try updating your XML files or romsets.
in other m1 news i have Gradius 2 x68k booting for the most part but for whatever reason the program returns into what is supposed to be the stack and locks up. it's probably a memory read/write error that has caused stack corruption or something.

- here's the latest version. all it does is add support for snatcher and not much else.
here's the xml for snatcher if you're interested:
<game name="snatcher" board="Snatcher (PC-88)">
<description>Snatcher (PC-88)</description>
<year>1988</year>
<manufacturer>Konami</manufacturer>
<m1data default="1" stop="0" max="255"/>
<region type="cpu1" size ="81920">
<rom name="PATCH" offset="4000" size="110"/>
<rom name="LOADER" offset="6800" size="14848"/>
<rom name="DRIVER" offset="D000" size="7552"/>
</region>
<region type="user1" size="98304">
<rom name="MUSIC" size="56540"/>
<rom name="MUSIC2" offset="E000" size="11970"/>
</region>
</game>
it's nothing more than a direct port from hoot, but there you go
- x68k almost figured out by unknownfile at 6:50 PM EDT on April 7, 2010
- there are some errors when returning from interrupts. for whatever reason, the rte opcode gets this off the stack:
Jumping back to 0B1A0000 (SP = 00F0FFC0)
i'm guessing it's either bad byteswapping or bad everything.
__________
Gradius II is now up and running. The driver has the following problems:
1. The timing is wrong.
2. No PCM chip emulation.
3. The binaries need to be patched before you load them.
I'll get back to work on this later, as I got other shit I should be doing.

- it gets worse by unknownfile at 4:19 PM EDT on April 8, 2010
- Looking at the X68k PCM situation. Hoo boy.
What they've done is alter how the PCM chip is controlled via patches. Usually the MSM6258 chip is fed data which it then outputs, but what the patches do is feed the code offsets and status registers. This way, it is easier to control and is a bit more like a MSM6295, but it makes it more annoying to hack away at.
- VGMToolbox r636 Released by snakemeat at 12:08 PM EDT on April 9, 2010
- VGMToolbox r636 released, grab it on Sourceforge. Here's what's new:
-= NEW =-
[VFS EXTRACTOR]
- Add a Virtual File System (VFS) extractor. Useful for extracting large container files that have a file table included or in a separate file.
- Sample plugins have been included for reference purposes.
[PSF2 SETTINGS UPDATER] Add a tool to change the psf2.ini file in batch mode for easy set-wide updates of parameters.
[SONY ADPCM RIPPER] Add Sony ADPCM Ripper. Tool is still WIP and may produce imperfect results.
-= UPDATED =-
[CD-XA EXTRACTOR]
- Add two-pass option for files that do not have silent blocks between reused block IDs. Use this when multiple tracks are extracted in a single file even when the silent blocks setting is set to 1. This option will determine a ceiling value for the distance between blocks and split tracks where that value is exceeded.
- Modified to clean up silent blocks, so extraction process doesn't leave a folder full of small, empty files.
[MKPSF2 FRONT END] Add option to create .psf2lib files to simplify creation for small groups.
[PSF DATA FINDER] Improved handling of small samples (less than 0xA0 in size), partial matching will now be used to try and match VB data to VH data.
[PSF2 DATA FINDER] Improved handling of small samples (less than 0xA0 in size), partial matching will now be used to try and match BD data to HD data.
-= FIXED =-
[PSF2 DATA FINDER] Fix code to prevent extracting the same BD section repeatedly.
-= PLUGINS =-
[ADVANCED CUTTER]
- Add PS2 KCES/SVAG plugins (bxaimc).
- Add XBOX360 tri-ace SO4/Infinite Undiscovery XMA plugin (bxaimc).
-= SOURCE ONLY =-
[MANAKUT] Add manakut.exe tool, a binary cutter with some useful options.
[VGMT INFO] Add vgmtinfo tool, a small tool to output tag info to console for all supported formats.
-= THANKS =-
bxaimc: Thanks for the new Advanced Cutter plugins.

- PlugNinja just updated nearly all of his plugins! It appears that the synchronization issue in the SNSF plugin has been fixed and other general improvements have been made to the other plugins. There is also a new QSF plugin available. But enough talk, go get them.
