I've been setting up several batch files to start Daphne in my multigame machine and I've come up with the following problems :

- Dragon's lair 2 V.2.11 to V3.14 : game either not completes boot sequence or starts but it is impossible to insert a coin (looks like freezed with attract sequence running)
- Dragon's lair Beta 2 : game looks for rom files with names dl_x_u1.bin to dl_x_u5.bin but files in lair_x.zip have different names, thus not starts
- Dragon's lair 2 V.3.17 : game starts but reports this:
ERROR: Unknown game type specified : lair2_317
Bad command line or initialization problem (see daphne_log.txt for details). To run DAPHNE, you must specify which game to run and which laserdisc player you are using. For example, try 'daphne lair noldp' to run Dragon's Lair in testing mode.

Also in "roms" folder I cannot see lair_317.zip.

I have also problems when trying to play early versions of USA Dragon's lair, particularly the ones that use PR-7820 as laserdisc player (wrong attract sequence duration, timing of moves is off). Are there any specific settings so that VLDP can better simulate the behavior of the original player ?
Can anyone please confirm these problems and/or help ?
So far I've only put in place a workaround to fix DL Beta 2 rom issue, by extracting the roms in roms\lair_x and renaming them as Daphne expects.
Thanks,

Matteo

I'm using the latest Daphne version, i.e. v1.0.12.
I'd like to report a few minor issues I've noticed:

- MACH 3 CPU emulated audio is missing one channel. Or it might be that there is a problem with timing of the playback. Just guessing here. You can hear this problem very well during the hi score enter your name screen. The correct music played there can be heard briefly in the last seconds of this video.
- Again on MACH 3, if attract sound is enabled, you can hear the "cruising" sound of the plane flying just when the attract sequence video starts and "MACH 3" is displayed on screen. In Daphne you don't hear it. If I have sometime I will make a video of my cabinet which is (was!) still running with original HW.
- When I run a game for the first time on my laptop, the video file parse starts.The video parser bar uses all the video area which is 1366x768. After parsing is done, the game starts in fullscreen mode and the left and right part of the video area still show the parser bar. So it's missing a video area clear before starting the game.
- Again on my laptop, if I launch a game that has a warning message at the beginning, I see the "This game's emulation has know problems" message aligned to the left of the screen, using about half the horizontal size of it, while the text warning related to the particular game is centered in the middle of the screen.

Hope these can be fixed at one point in the future.
Thanks for reading.

Thanks, Teo.

I actually knew about the MACK 3 audio bug and you are the first (and only) person to report it. I was wondering if anyone would ever find it hehehe. The audio used to work but then in the final version of the sound code that MarkB did he broke it somehow. I've always intended to go back in SVN and see what he broke but never have.

onward with Dexter wook

OK, Matt.
I also wanted to report an incorrect timing in DL2. The boot up sequence plays faster than the original machine. Also the hi-score enter your name screen has the blinking way too fast with respect to the original. It looks like there is a temporal emulation of the whole machine which runs faster than the original. Not sure if this has also an impact on the actual gameplay. If I have sometime I will make some YouTube videos of my machines so to show what the original behaviour looks like.
Keep up the good work, with both Dexter and Daphne hopefully.

I found another bug in Daphne that causes a crash.
Steps to reproduce:

- start Badlands
- play a game
- get a decent score (for example > 20000)
- enter your initials in the hi-score table after game over
- let it run idle in attract mode

After some attract cycles Daphne will crash. I've seen this happening on three different machines.
The relevant part of daphne_log.txt after the crash is the following:

All good finds, thanks Teo

While testing out a couple of euro ROM revisions I've recently been given, I found another problem in Daphne related to DL2 emulation. I tried to run V.3.12 euro as V.3.19 in Daphne by disabling the CRC check and renaming the files as required by Daphne, however here's what I got:

Could it be a problem of the non volatile memory that needs to be reset since I've changed the ROM from 3.19 to 3.12 which perhaps uses a different eeprom format?
