Index of Freeplay, High Score Save, and Bugfix mods

I've been files for the collecting the subject types of hacks/mods for a little while, and the folder started getting out of hand, so I created myself an index of what I've got. Just thought I'd share the list.

Let me know if there's something else out there that I've missed. Note that I'm not including "for-money" stuff here. I'm not here to advertise anyone's EPROM/kit sales site(s)... This is stuff I've found free-for-sharing around the 'net (with one exception). It's limited to that which can be done with just an EPROM swap and perhaps a NVRAM installation; those that require daughter-PCBs or "kits" are not listed.

Matt also did a screen flip mod for Crazy Kong, so it'll display the same as most other games (CK is upside down compared to most other games)
 
You missed all of Jrok's high score saves
(Bombjack, Super Pacman, Mappy, Mr Do, Pengo?, probably more)

Pole Position II HSS
(Just replace a socketed RAM with a battery backed RAM)
 
Thanks, guys. Here's the updated list, with additions per the above:

I think someone did a free play for Satan's Hollow. But I don't remember who. If anyone knows who sells those, I'll buy one TODAY!
 
I did a few others not in the list... they're here
DogP

Thanks for the additions and clarifications!

I also found another one (Ikari FP), and the last remaining "unknown" (Reactor is JROK).

PS @ cwilkson & 30FathomDave: I can't locate a Satan's Hollow HSS, so I didn't add it to the list.

I don't know who but I remember reading that someone came up with a Bagman cheat hack for like enhanced player speed or something, adding custom diagnostic EPROMs to the list might be cool too, I've seen them for Sea Wolf, Spectar and Targ, and maybe suicide battery defeat/custom CPU bypass hacks for like Golden Axe, Shinobi, Aurail, Turbo, and Altered Beasts.

There is also a preliminary EPROM control hack for Strike Force which makes it control like Defender(a HUGE improvement I guess), again off the top of my head I can't remember who made it.

Souzilla did a Karate Champ HSS kit (player vs. player). There are still some bugs to work out, but it's functional.

EDIT: sorry, missed the part about free kits only!

No, but jungle king would not be that difficult to make if people were interested.
I just had some time on a plane to I did this. Not sure if I will have time to do jungle king anytime soon.
 
Galaxian HSS... ?

I've seen a high score save kit for Ladybug on Ebay, I don't know who makes it though.

Galaxian HSS... ?

Re Ladybug and Galaxian HSS: To my knowledge, these are both non-free kits, requiring a PCB assembly to be purchaced. See my original post (quoted above here) to clarify what this list is intended to include.

I have nothing against non-free kits. In fact, I own several of them. It's just that I'm a strong supporter of sharing modded code for free. I'm such a strong supporter, that I offer for the code free of charge for the HSS hacks I've made. (I only sell the LE kits as a convienence to those who can't, or don't want to, program the EPROM themselves.)

Anyhow, my list was partially intended to support and encourage those who share their code/instructions/hacks/patches/etc freely. If someone wants to make a list of all the non-free kits (Braze, souzilla, Jeff's Romhack, etc.) I would request that it be in a seperate thread.
 
Discs of Tron sorta has a free play/bug fix available here:
http://www.ionpool.net/arcade/mcr/dot/index.htm

It's noted that it was created for the EDOT or a UDOT with a speech hack, so it will cause short delays in a non-speech enabled UDOT where the speech would normally be. It does fix the bug on earlier ROM revs where TRON can fall off a disc after the 2nd Sark on a level has been beat. It's actually a patch for the ROMs and not full images of the patched ROMs themselves. The author notes that if someone wants to edit the patch to make it work with a non-speech UDOT it should be possible.
