This is easy to fix.
1. Export the sound clip with an earlier version of PB or Use whatever sound capture software you're comfortable with
2. With Audacity use the "change tempo" modification. This will keep the pitch the same. Double the time of your "chipmunk " clip. The result will be exactly what you want and expect.
3. The clip was also down sampled. Try decreasing 1 to 3 do and then boosting the sound with the "compressor" mod. You'll need to experiment a bit.

Had this issue several times colorizing SMVE with daily incremental updates. The file somehow became corrupted.

Only way I could resolve it was to start with a virgin binary file and patch it with the comm patch before doing anything else. Set the patched binary for serial side channel. Reload all changes via the macro.

If you load subsequent things to the binary through macros, either take out the comm patch line from macro or comment it out with "--" at the beginning of the line. Either way you will get an error "cannot locate ..." Just click through and the rest of the macro will run.

Not sure if this will work for the new MET patch but it did for 1.0. SMVE and the subsequent update.

Sorry thought you were doing color. Your best bet at this point is to contact Olivier for help.

Yikes! This is bad news for everyone working on home brew color solutions for their games knowing the it is possible the future code updates will preclude them from using the side-channel color palettes.

Not being able to make remote adjustments to scores would be inconvenient but losing the side-channel color would be heart breaking.

I can report that the comm patch still works with the recent SMVE 1.01 update.

Follow Olivier's notes.
I spent several days pulling out my hair trying to get the serial side channel to work, until I understood the process.
1. Start with your virgin binary file for your game.
2. Load the comm patch that is included in the Pinball Browser folder before you do anything else.
3. After the binary file is patched, configure your PB for serial side channel.
4. Have fun colorizing

Great news. Hopefully I'll be picking up a MET soon.

Thanks oga83 and Sirlonzelot for working together to get this updated version out!

yes, your previous license will work.

I've done lots of call out mods and modified the closing music to include the original animated theme fade in and out.

Not hard but a bit time consuming reloading the binary

Metallica - yes, if Hero of the Day is longer than Unforgiven it will end at the length of the Unforgiven song. If Hero is shorter, you'll have silence at the end of the song making up the time of the full Unforgiven song.

Ghostbusters - I don't have experience with Spike games. But according to the OP, in the very first post (https://pinside.com/pinball/forum/topic/acdc-display-and-modify-dot-matrix-images#post-872012), Pinball Browser should work with Spike. The same clipping/silence would apply if the replacement song is longer/shorter, respectively.

I believe .pbi is specific to the software. Image export (in a standard format) was removed at one point and later added back into the software. Possibly copyright issues.

Have you tried reducing the peak levels? I’ve experienced popping in the past using audacity and reimporting.

Once I adjusted the max volume levels downward in the clip, the popping stopped.
