Did you disabled?

You need to enable cheats to make them appear. (That's also the reason I was unable to find the sliders until a few weeks ago.)

You can do that by either editing mame.ini and set cheat to 1 (CORE MISC OPTIONS section) or you run MAME with mame.exe -cheat.


@all: I forgot to include a mame.ini. You can generate it with mame.exe -createconfig

Hi, I would like to work on some rips, but I have a couple of questions. Hope someone can help me.

I'm interested in games using the Qsound chip, I have downloaded the latest MAME mod, enabled the option to rip vgms in the ini file. Then I enter the sound test and start playing the songs. But when I exit the emulator, I can see only one vgm file is generated, is that the expected output?

Do I have to rip one song at a time? And is there a tool to automatically find loop points? Or do I have to manually set the song length and loop points, etc.

Thanks in advance.

MAME writes one file for one game, usually you record all tracks together an then split them with tool. Yes there is tool for finding loops, tale a look at VGMTools thread. Also feel free to visit IRC channel for assistance.

Rohga is Audio CPU HuC6280 is not 2.685MHz, I think probably 10.740MHz.
I want to set to 400% Overclock CPU. (The current can be set up to 200%)
Can you add a setting like that?

I'll see what I can do...

Anyway, according to M1 it is 32220000/8=8055000.
MAME says 32220000/4/3=2685000 and says it was verified, but the comments say something about 8.050 Mhz, so M1 is probably correct.

According to some of HuC6280 clock is 21477270/3=7159090 "source (Timer.cpp)" of Ootake.
I seem to let the operation clock is divided by 3.
I'm a slow tempo it clock 8055000.
I think I might become the correct tempo 32220000/3=10740000.
I think it will be fit also calculate YM2151 the clock 3580000x3=10740000.

sample Rohga - Demo:
http://www.mediafire.com/?vieu9tn7gxh27fc
rohga_ost.mp3 is Sound Track CD
rohga_hoot.mp3 is Hoot Recording (Tempo is faster than the OST)
rohga_M1.mp3 is M1 Recording (Tempo is slow than the OST)

I seem to be operating above the clock 10740000, I do not know of Hoot.

Edit:
I've found a video that was recorded from the actual arcade board.
http://www.youtube.com/watch?v=6KhqOP1KrNg

It is a sample of the data recorded in MAMEPlus. (MAMEPlus can be set to 400% Overclock CPU)
http://www.mediafire.com/?bkuabhcxrjer5ck
Rohga_300%.mp3 is 300% Overclock CPU (8.050 MHz)
Rohga_400%.mp3 is 400% Overclock CPU (10.740MHz)

I seem to be running at 10.740MHz Judging from this video.

2ch-H, I noticed some of your more recent packs were dumped using ValleyBell's MESS mod. Despite enabling the vgmwrite flag in the mess.ini file, I can't seem to get it to log a VGM from launch using the NEC PC-9801RS and related targets. Am I missing something?

I use the MESS148, vgmwrite flag of ini/pc9801rs.ini is enabled.
I think it's VGM output possible.

Mess vgm output Bug?
Mess is giving errors at the end by playing a specific song.
vgm that is output is not normal.

This VGM sample, Journey to Silius - Opening:
Edit : I deleted the file

Code:
0x00028549: 67 66 C2    Data Block - Type C2: NES APU RAM Data
         Data Length: 0x00000A91      Write to Address: 0xFC00

I guess it uses one of these tricks where the DPCM sample crosses the border of the memory area.
MAME/MESS doesn't handle that correctly (because I read about that behaviour after adding NES logging).
Also, VGMPlay crashes at the end, because the data block writes beyond the bounds of the RAM array. (and I didn't catch that - I do now) Something similar probably happens in MESS, too.

I'll try to fix this with the next MAME/MESS update.

EDIT: Ah, no. I think that just the way my logging works is a little buggy.

i have problems with mega cd emulation using mess 0.148
i want to rip some games (tried snatcher & urusei yatsura), but none of them worked
i have mega cd (or sega cd for snatcher) bios running, tried to browse to the iso file, it says "push start", then, it crashes mess completely
i even tried to read directly the CD, did not work
valleybell> how did you rip sonic CD ?
do i need to transform the cd into chd file, like it's done for mame cd or hdd games ? if yes, anyone knows a tutorial about it ?
thanks

Gens GS/R7+ will do SegaCD/MegaCD rips as well as 32X. Although it still seemed a bit buggy last time I tried it.

Gens GS/r7+ worked very well with Sonic CD. I also did Popful Mail with it.
32x should be fine, too.
The only bug I noticed was when ripping Knuckles Chaotix, where it sometimes missed to play drum sounds, but I later found out that this is a bug/race condition of the sound test screen. (It works well during the rest of the game.)
