Many Meteor owners might be familiar with Oliver Kaegi's 7 digit update to meteor. (http://www.pinball4you.ch/okaegi/pro_soft.html)
This version unfortunately has a couple bugs - it suffers from the 'collect all rockets' bug, where you get a 256x bonus multiplier on countdown, and it has a visual bug when you start the game, you get 000 instead of 00 (minor, I know, but still irked me).
Details of RGP discussion on collect all rockets bug:
There was an aborted attempt over the last couple years to re-write the game framework into a newer, native 7 digit classic stern OS - Big Game was that OS (since it's the first 7 digit game and closest to meteor) - while this was successful, it introduced a new, kind of serious bug - a problem with the sound getting clipped. Various things were tried to fix this... see: https://pinside.com/pinball/forum/topic/stern-meteor-rom-issue-bugfix-sound-issues-nvram-discussion/page/2 about midway down the page.
So, back to the original Oliver codebase, fixed the addition of the zeros where they shouldn't be (properly, this time.... not in the display interrupt), and then re-rolled the other goodies back in.
These goodies are:
triple zero quash in 7 digit version
faster replay level setting (ok this is minor, but it takes FOREVER with the stock interval to get >1,000,000 for settings)
add function in outhole to test if the spinner is stil spinning to avoid losing score
add dip #19 to turn on/off free play
add dip #17 to turn on/off 25k drop sweep bonus (any rocket bank 1-2-3 you sweep gives you 25k extra)
add sound nvram clear to bootup (see pinside discussion linked above)
player add after score zeroes previous player displayed score (see pinside discussion linked above)
added spinner counter similar to big game's mod/dragonfist (this is REALLY cool.... I've gotten almost 90 spins a couple times)
bug fix for collect all rockets (see RGP discussion as well as pinside discussion both linked above)
test drop banks at ball launch, only reset if targets down
dip 16 on=pay 3 specials for hstd, off=pay none (15 freed for future use)
And, as an added bonus, if you don't need/want to update your meteor to 7 digit displays, the above goodies can be compiled into the 6 digit codebase.
So, I am compiling a list of people who can BETA test this, and specifically 6 digit owners that might want to try this.
Requirements are that you have a rom burner or a way to burn roms, and the requisite eproms. (I recommend 2x2732 in an mpu200, if you have a weebly mpu board with the combo rom, you can use the 512 socket with a 512 eprom in it.... if you have an alltek you are out of luck as they do not publish/support changing their eprom)
I will be more than happy to send the compiled code to interested parties; I only ask that you test it out and post feedback here. There are a couple other things I'm going to add (unlimited specials, because I like the pop, reminds me of old EM's) and maybe a couple other things, not decided yet.
The current version branch is "72B" for the seven digit version, and "62B" for the 6 digit version, which gets reported minus the trailing letter on the match display on bootup.
After a sufficient period of beta testing, I plan on distributing the source code as part of the on-again, off-again classic stern disassembly project. Write a new custom game using old hardware! No P-Roc needed.
PM me your email address so I can send you the rom files in the format you need them (6 or 7 digit, 2x2732, 4x2716 (not recommended due to 2716's being difficult to get, many won't burn well), or 1x27512 [for Weebly's board with the 512 socket])
