Hi! Here are the screenshots of various tests tools running on my actual Spectrum +3. I can confirm that my mame implementation (when running the 'specpls3' model) displays exactly the same test results as the actual Spectrum +3, *except* for the "Test: Contended NOP" test. According to my actual Spectrum +3, during the Contended NOP test, TState 14490 takes '5' cycles. This differs from my mame implementation (and the Fuse emulator) which both indicate this as being '4' cycles. Which is quite interesting...

Right you are, however the model number is right, and the 2 indicates MMG, so I will update the table.

Modeler and M1

Hey

Sorry for the long first post smile

Have been using M1 mainly to listen to Pinball ROMs, my Dad and I are avid pinheads. I also have an interest in retro-emulators mostly using RetroPie on the Pi.

I've wanted to add a few new Pinball machines to M1 that are not in the default list, these are "Williams Pinball CVSD" machines. I tried a few times and thought it just wasn't going to work, however I managed to find the offsets in the MAME source code for the missing machines.

I am a bit confused about entries that include multiple lines for the same rom file eg. here is the XML for "Twilight Zone" which is included in M1.xml by default. Notice that rom tzu14.. has four lines. Is this basically loading the rom four times into a 524288 allocation? Also noting this all correctly adds up to the total 1572864. (3x 512k)

So I tried to get "White Water" working ("ww_l5") I found a snippet of source outlining the sound roms from https://github.com/mamedev/mame/blob/master/src/mame/drivers/wpc_flip2.cpp
Code

But I'm not sure what to do with the last offset as setting this looks like its overlapping (?).. Maybe I'm not understanding this correctly.. I'm assuming that we're basically concatenating the ROM files into one logical block from 0 to 1572864.. I'm sure I've just stuffed up the HEX.. but each time M1 reports out-of-bounds for ww_u14.l1?

This does work, but seems to have several issues.. any ideas?

Thanks

Ok fixed!!!! Ive been trying things all day and came back to re-read your guys responses. Haze mentioning it wasn't in my ROM path clued me in. I thought the swpath entry in the ini file was where the software roms were located?? I added "software" to my rom path. I was already in the MAME directory in the terminal but I ran ./mame nes -cart smb2u just to be safe, and IT WORKED!! Tried it again without the ./ and it still works!! It only works either way if Im in the MAME directory though. I have the root folder in my path so I can just run mame64 from the command line and play arcade games, but it ONLY works from the command line.. I fired up the MAME GUI, and no dice. Somehow my favorites keep getting wiped out, but when I found and clicked on the NES, it's doing the thing again now where it doesnt open the software list, and wants me to browse to a rom to open, but it won't/can't open them!!! They're working great in Negatron now that I added 'software' to the ROM locations. I don't remember ever having to do that before but maybe I did in an old install. They were just working a few versions ago though, but that was in QMC2 also.. Still don't remember having to put them in the ROM path though. The software path worked for it.

EDIT: Nevermind, MAME magically works now too! Just reopened it a few minutes ago, and now its showing the lists again, and both Castlevania 2 and Donkey Country opened up in MAMEs own GUI! Simple fix for a stupid oversight I guess. Maybe I just needed to relaunch MAME after I changed the rom path or something?

I still think a timer per character cell is going to be a lot of overhead. All the CPUs and various other things like the POKEY sound chip implement device_execute_interface. If you go this way, you can cause synchronisation when things actually change rather than running a pessimistic timer.

Alternatively you could use a timer that triggers at the end of a scanline, but trigger partial updates when something happens that affects rendering. You can check the time in the current executable device's domain at the point where you get a register change etc. to work out how far through the line you are. This would work well enough if only a single executable device (e.g. CPU) can cause register changes,

MAME 0.199

Today’s the day for our mid-year MAME release. MAME 0.199 includes support for the incredibly elusive Spanish arcade title El Fin Del Tiempo, and the rare Pac-Man hack Titan. Other rare bootlegs added include Come-Cocos (derived from Ms. Pac-Man) and Gran Rally (a Spanish bootleg of Pole Position II).

There are some pretty big improvements to Tatsumi games (Apache 3, Cycle Warriors, Round Up 5), some NMK mahjong games work substantially better (Urashima Mahjong, Mahjong Daireikai, Mahjong Channel Zoom In), and Big Run looks better than ever. War: The Final Assault no longer crashes thanks to a fix in Voodoo emulation.

Floppy drive emulation has been further improved, and a fairly major issue with Apple IIgs and Mac 3.5" drives has been fixed. Sound Blaster direct DAC mode is now supported. Improved Dreamcast GD-ROM emulation allows Daytona USA 2001 to boot. The HP 9000/300 series can now boot from floppy, and the medium-resolution colour graphics option is supported. Tiger Electronics fans can enjoy Battle Arena Toshinden for R-Zone.

Of course we’ve also added more alternate versions of supported systems, software list updates, bug fixes, and internal improvements. You can get source and Windows binaries from the download page.

I don't think so. Mame can do it, however:

-verifysoftware [<gamename|wildcard>]
Checks for invalid or missing ROM images in your software lists. By default all drivers that have valid
ZIP files or directories in the rompath are verified; however, you can limit this list by specifying a specific
driver name or wildcard after the -verifysoftware command.

So I'm thinking that it might not be hard to implement, in QMC2. But execution might take a very long time, which is why I suspect that option is not available.

I also think startup time (always a concern) would be significantly impacted, reading in a huge sl state cache. So better to just check the roms in use, between sl updates.

I don't mind hitting f10, if/when I decide to play some new sl. I'll admit, though, once or twice, I have also thought: "Wish I could do them all, at once.".

Hi,

I'm working on implementing the custom cassette-drive used in the Intellivision Keyboard Component.

I have a question about the way updates() happen - I'm looking for some architectural direction smile

The tape drive can generate interrupts for every decoded bit, nominally 3000bps. Some other drivers (such as the TRS-80) use a higher speed, periodic update function which examines a section of the tape on every update. For example, I could set up a 24000bps timer which looks at the tape, and if there is cause for an interrupt (like the end of a bit), it would generate it. The worse-case latency then is something like 1/8 of a bit, which is probably ok. Obviously, increasing the rate would lower the worse-case latency.

Another approach I thought of would be to set up a timer to go off when the next tape event is (probably) going to happen. At that time, I could process the event (generate an interrupt), and do a "look ahead" of the tape data to setup the timer for the next event. This seems a bit tricky, and I haven't seen a driver that does this, but it would do exact timing and seems like it would work really well.

Does option 2 make sense to anyone else? Am I missing something? Should I go with the first solution because of an issue I'm not seeing?

Thanks for reading!

Working on C64 support for samdisk... The same GCR encoding and similar zoned format was used later on Victor 9000.

Also found and hopefully fixed a bug in HxC's GCR encoder - this should let me write d64 images via SCP card.
