Since the release of MAME 140u2, we (nimitz, austere, and I), have been
working non-stop to increase the accuracy of the Cave PGM for you.
Today we are proud to display our work, which has the following changes from
main-line 140u2:
1.Cave PGM games have been moved to be a subset of pgm, so that manipulating
the romsets is not required.
2.ASIC027A ARM code simulation has been removed in favor of proper emulation
of the ARM (so that usage requires a dump of the internal ROM, or an
alternative such as ASick72 [see below])
3.ICS2115 emulation has been greatly improved, however very small issues with
sustain and volume still exist
This work has been great fun for us, and we hope you enjoy the product of it
as much as we enjoyed creating it.
As a side-product of change 2, I had to recreate the simulation in actual ARM
code. This new code is called ASick72, and so far, recreates the Cave ROM
perfectly enough to run all 3 Cave PGM games with no issues.
And now for some links:
‧MAME Patches: http://www.raidenii.net/files/cavepgm.zip
‧ASick72 (with binaries): https://github.com/SquidMan/asick72
Many thanks go to the testers at #iustek, #raidenii, #shmups, Shmups forum,
and MAMEdev.
Please, send all donations not to here, but to Dr. Decap. He is far more
important, providing constant, accurate and very important emulation
resources. His website is at http://decap.mameworld.info/
