Sorry to hear you have trouble with that sound. Let me assure you that I put LOTS of efforts in time into that subproject to make it somewhat believable, and I still believe it to be one of the most valuable additions to MAME. For more detail, see the explanations on https://www.ninerpedia.org/wiki/MAME_Floppy_sound_emulation.

The sound in UAE was one of the features that made me interested in emulation, and was one of my dreams to realize in MAME.

That said, I know the sounds are not liked by everyone, but frankly speaking, what I do have some trouble with is when people treat it like some nuisance or imposition when it just suffices to ask whether there is a way to turn the sounds off or to lower their volume.

You can turn down the volume in the Sliders menu.

(Sorry if I react a bit harshly, but you're not the first one, and I seem not getting used to that over time.)

sorry, i am noobie when it comes to using mame. -- and i not used to the old-school floppy sound, been a while, all my real hardware ti99 systems have much quieter 5.25" and 3.5" floppy drives, i stopped using the large full-height original floppy drives from ti for a while now. -- plus the tiny tin speakers on my laptop are horrible, can't even listen to youtube on them.

so how do i access the sliders menu? to adjust the volume?

Open the MAME OSD menu (the main control window of MAME) by pressing TAB in "UI controls enabled" mode. This mode is toggled by the ScrlLock key; please refer to https://www.ninermame.org/using/keyboard/uimodekey for more information if you want to use another key for that.

In the OSD menu there is the selection "Slider controls", the channel is named "flopsndout" (for each drive). I actually have it at 60%. Note that since there is no visible feedback in the emulation, those sounds may be the only indication that "something is happening".

What no blinking LEDs for the PEB cards. Just joking. Maybe someday. Also does the floppy sound change to a hard drive sound? If it's different device being accessed. Still haven't figured out how to get speech working even tho the speech roms are there. I guess that a command option in the batch startup.

Yes, "artwork" is an existing MAME feature (for Arcade machines), so this may be feasible.

I considered this indeed, but it's a bit more difficult to get good sound samples. Only the old Seagate drives are loud enough to deliver good sounds.

In MAME, the Speech Synthesizer is modeled as a PEB card (device "speech"). Some time, I'll add a sidecar Speech Synthesizer.

mame ti99_4a -ioport peb -ioport:peb:slot4 speech ...

Is there a option for the Corcomp triple tech card to add clock and I guess that would not include speech so it would be two slots on the PEB?

+mizapf · May 5

Corcomp TripleTech is not yet emulated. I may add that some time, but the next thing for me is to complete the SCSI emulation (block DMA).

Current scope of emulation: https://www.ninermame.org/info/scope

+mizapf · June 2

New MAME release here (0.266).

There are two fixes for us:

1. The Horizon Ramdisk is now properly reset when the system is reset. This especially means that the two latches on the card are cleared.

2. The "Future SRAM expansion" area of the physical memory map of the Geneve is now properly assigned to on-board access and does not send accesses to the PEB anymore.

The pre-built binaries can be found, as usual, on our WHTech server:

Linux: https://ftp.whtech.com/emulators/MAME/ti99/linux/mame0266b_ti99_linux64bit.tar.gz

macOS: https://ftp.whtech.com/emulators/MAME/full/macos/mame0266b_macos64bit_arm64.zip

RPiOS: https://ftp.whtech.com/emulators/MAME/ti99/rpios/mame0266b_ti99_rpios64bit.tar.gz

Windows: https://ftp.whtech.com/emulators/MAME/ti99/windows/mame0266b_ti99_win64bit.zip

Edit: I built the Linux version for an Ubuntu 24.04 LTS. If you get problems with older OS releases due to library mismatches, you should build MAME from sources. Maybe you should build it from sources, anyway. That is, even if the binaries are working for you. Ask me for details if you are interested.

Michael,

I have pulled the linux and rpios versions down, and if I am doing everything right, the 2.66 versions are showing up as version 2.64.

Is this an issue of not updating the version number, wrong files were selected, or am I doing something wrong?

+mizapf · June 12

Maybe I checked out the wrong version before building. Thanks for notifying me!

I just checked the history, and no, the correct versions have been built. You should get a 0.266 release from the above links. I just tried it for Linux and RPiOS, and I do get 0.266 as intended.

Interestingly, I did not build and upload a 0.264, so I cannot really explain why you see a 0.264.

OK, will investigate more.

Hi,

I tried to update from .256 > 266B, on Windows.

Usual approach, pull over zip, unzip, copy and paste in to mame dir.

When I try to start, I get,

D:\mame>mame genmod -window -oslog -bios 1.00 -peb:slot3 horizon -peb:slot5 tirs232 -peb:slot6 tipi -conn rpi.192.168.2.213 -peb:slot8 hfdc -peb:slot8:hfdc:h1 generic -peb:slot8:hfdc:h2 generic -peb:slot8:hfdc:h3 generic -peb:slot8:hfdc:f3 525dd -peb:slot8:hfdc:f4 525dd -hard1 genos7boot.HD -hard2 Bootdisk2.HD -hard3 Bootdisk3.HD -flop1 DM1000SRC.dsk -flop2 DSDD2.hfe -flop3 DSDD3.dsk -flop4 DSDD4.dsk -serl1 socket.localhost:10000

tipidsr_2023.u2 NOT FOUND (tried in ti99_tipi genmod)

Fatal error: Required files are missing, the machine cannot be run.

Everything started OK, before the copy, paste.

+mizapf · June 16

You should get a new copy of ti99_tipi.zip from WHTech (https://ftp.whtech.com/System ROMs/MAME/).

+hloberg · June 16

the EVPC setup seems to crash every time I try to change cartridges. cartridge change seems to work fine with TI99_4A with the same setup.

attached is the .ini & the EVPC rom I use (might be old).

Here, the batch:

@cd mame0266b
@capson
@type sskeys.txt
@mame ti99_4ev -inipath ini/ev -window -uimodekey F11 -skip_gameinfo -autoframeskip -natural -ioport peb -ioport:peb:slot3 tirs232 -ioport:peb:slot4 speech
@capson
@exit

attached is the .ini

ti99_4ev.7z ti99_evpc.zip

+mizapf · June 16

I can confirm the crash. This seems to be related to a type mismatch between the (non-existent) TMS 9928A and the v9938 on cartridge insertion. Interestingly, it does not happen when I reset the emulator with F3.

My suggestion is to avoid swapping cartridges during runtime until this is fixed. You can start the emulation with the desired cartridge inserted in the command line.

will do.

+mizapf · June 16

Fixed; it was even simpler. I expect it will be available with MAME 0.267.

                m_cpu->set_input_line(INT_9900_RESET, state);

 }

I'm sure this is not a new bug; it could have been there for years. It only occurred when the console RESET line was triggered, which is by the cartridge port.

I downloaded the new tipi.zip, farther along, but I lock up here:

+mizapf · June 16

I guess this is from the command line above, a Genmod. And you are still running a serial bridge on your localhost at port 10000 (as stated in the command line at the end).

Why don't you use bios 2.00? Is your TIPI also updated appropriately?

I suppose there are no further lines, but for easier debugging, use "-log" instead of "-oslog" and post the error.log here. This is much easier than doing screenshots.

+dhe · June 16

No particular reason that I'm using bios v1, instead of v2.

After removing -serl1 socket.localhost:10000 everything boots, and I am able to do a tstat which shows no tipi updates are waiting.

I think the reason I put in -serl1 was so I could communicate over the serial port or write to the serial port and save it to a file.

error.log

Everything started up with my config file with using .256, maybe mame tightened up on the -serl1 parameter?

Attached is the start up log with -serl1 add back.

mame genmod -window -log -bios 1.00 -peb:slot3 horizon -peb:slot5 tirs232 -peb:slot6 tipi -conn rpi.192.168.2.213 -peb:slot8 hfdc -peb:slot8:hfdc:h1 generic -peb:slot8:hfdc:h2 generic -peb:slot8:hfdc:h3 generic -peb:slot8:hfdc:f3 525dd -peb:slot8:hfdc:f4 525dd -hard1 genos7boot.HD -hard2 Bootdisk2.HD -hard3 Bootdisk3.HD -flop1 DM1000SRC.dsk -flop2 DSDD2.hfe -flop3 DSDD3.dsk -flop4 DSDD4.dsk -serl1 socket.localhost:10000

+mizapf · June 17

The point is that the "-serl1 socket.localhost:10000" instructs the MAME core to set up a socket connection to the destination localhost:10000. This in turn requires you to run another process that actually opens such a socket.

The problem is that this code in the core is not very robust; when it fails, the error is not appropriately handled. I noticed that this was the cause of crashes in earlier MAME releases; right now I see that I'm getting an image error when I try it without an opened port ("Unable to load image 'socket.localhost:10000': Connection refused (generic:111)").

You can run TIImageTool to provide this connection using the "serial bridge". Its purpose is to link MAME with the real serial interface (may be a real UART if your mainboard still has one, or a USB adapter). Then you can connect this with another computer by serial connection (e.g. the real Geneve, as I did).

Long text, in short: Do you really need it? If not, better leave it away.

+dhe · June 18

FWIW - Discussion on using the serial bridge:

+dhe · June 22

@mizapf

I want to do some testing with gdm2k and IDE.

Can you sketch out for me how to setup and IDE drive with a Geneve, under MAME?

+mizapf · June 22

Do you already have a working IDE card (i.e. with installed DSR)? If not, you'll have to run IDELOAD first. Second would be to prepare a HD image.
