Not a re-translation, but more of an interpretation of what I think google was trying to say. lol
AWJ has recently implemented a core for the nec v25/v35 cpu, thanks to this the sound has been emulated in batsugun.
Batsugun does not use the feature of the CPU to encode the opcodes using a conversion table.
Unfortunately kbash, vfive, dogyuun, and fixeight do.
When analyzing the code you can see huge similarities between the code of batsugun and the other encoded ones. This has enabled AWJ and I to decipher most of the opcodes. The first result is that the conversion (decode) table for kbash, vfive dogyuun and is identical. Also, the code for batsugun and kbash is almost one hundred percent identical. In addition, the startup code of dogyuun, vfive, and fixeight is identical. For the last 3 there was more work because many opcodes have not been matched with opcodes from batsugun. Once decrypted, I noticed that the startup code for these three decrypts copy ram content in ROM [?]. Successive passes control to this new code, and again you start to see huge similarities between all 5 games [?].
Summary:
batsugun can decrypt kbash (almost identical code).
kbash allows you to decrypt and vfive dogyuun (same conversion table).
vfive dogyuun and allow decryption of fixeight (code almost identical but different conversion table).
Once finished with decryption, we can try an implementation of the sound.
*Any lines with [?] I was unsure of.

I read on a shmups.system11.org forum post that sound samples for Vimana were posted here at mameworld forums but I can't for the life of me find them anywhere. They were supposedly a Robiza project and by running Vimana in thundermame and playing these .wav files through a samples folder sound would function in game. Anyone have those files or know of a place to download?

It's true - only bgm, and I couldn't get the wavs to sync with my rom file. I might be able to after some research...but...
Check out this link. Includes active downloads of audio samples for Toaplan games V-V, Batsugun, Same!Same!, Dogyuun and Tekipaki. Vimana is however missing from this list. I can now play Same! with sound(unemulated is ok as long as it's more than just bgm).
Anyone have a complete collection of the vimana samples. Something similar to what the linked otaku site offers?

For anyone interested in playing the yet-to-be-correctly-emulated Toaplan titles, someone has posted a link to a sound samples download location. I'd been trying to find decent samples for awhile now of Vimana and Same!Same!Same!. Thank God and the uploader.
Here's the link to Shmups thread...
