I've collected together and stickied all the excellent freeplay and high score mods that the guys have put together. I'll add to this as the threads are produced. If I have missed one let me know.
1942 : @cmonkey
1942 free play with attract mode enhanced roms
Mr. RGP asked me nicely, so how could I possibly refuse! All the info is in the readme in the archive. Any questions, fire away. https://www.ukvac.com/forum/data/uploads/1497/1942_free_play_enhanced_patches.zip

AfterBurner 2: Enhanced Edition: @dj_yt
AfterBurner 2: Enhanced Edition
AfterBurner celebrates its 30th anniversary this year, so it seemed fitting to produce an ‘Enhanced Edition’ to offer the definite experience to fans of the original. AfterBurner 2: Enhanced Edition (AEE) is a set of 3 replacement EPROMs intended for use on the original arcade hardware. It...

Buck Rogers/Zoom 909 : @GadgetFreak
Buck Rogers / Zoom 909 High Score Save Patch
Finally dug out my Buck Rogers, having not powered it up for 20+ years, it had issues. So having fixed it and having to replace all three 2k ram chips, I decided it was perfect for a high score patch. My board is socketed with factory sockets so this could be standard for this board set. The...

Do! Run Run : @GadgetFreak
Do! Run Run High Score Save Patch
Another patch that you will need you to replace a ram chip, its the 8218 ram chip at H1 (next to the four program roms) with an NV version such as DS1220, M48Z02, U63716DC etc. Until I did this patch I didn't realise that this game keeps the top 50 scores even though it only ever displays the...

Donkey Kong : @RaveN
Donkey Kong Freeplay
Okay, I might be embarrassing myself here. I had people coming over and the only one of my machines still not on freeplay was the DK. I needed FP with the attract, and couldn't be arsed to buy another braze kit (great bits of kit, but I wasn't interested in the high score etc..) I did search...

Food Fight : @edwoodjnr
Atari Food Fight - Improved Free Play
Although Food Fight has a free play mode that can be set using the dip switch #2, once set you no longer see the fancy attract mode and the high score table is not displayed because setting the dip continually sets the number of coins inserted to 2. While you can wire P2 start to coin 1 with a...

Frogger : @philmurr
Frogger Freeplay / High Score Save
So I included Frogger in my Konami/Stern multigame around 6 years ago but never did a standalone freeplay / high score save kit. Until now. Most of the code was already done but it did need adapting to work on a Frogger pcb (with its different memory map), and with my high score save board...

Galaga 88 : @GadgetFreak
Namco Galaga88 High Score Save Rom Patches
As I had done Pacmania and my friend had a Galaga'88 he asked me to take a look. At the moment I have only done the main version listed in Mame as this is the one he has. The patch requires no hardware changes just like my Pacmania patch, just 2 eproms patched and reprogrammed To reset the...

Galaxian : @philmurr
Lady Bug : @GadgetFreak
Lady Bug High Score Save Patch
The easiest boards for this patch are the later Universal single boards (8106-II) or the bootlegs which seem to be copies of this board as you will just need to replace the 6116 at 2NP (next to the 2 sprite roms) with an NV version such as DS1220, M48Z02, U63716DC etc. If you have a Universal...

Marble Madness : @edwoodjnr
Marble Madness Free Play with blinking LEDs
This has been raised a few times previously on KLOV. After recently revisiting my improved Free Play ROM hack for Food Fight where I added blinking LEDs as per other Atari games I was asked to look at adding the same for Marble Madness. This game already has a Free Play mode that works well so...

Marchen Maze : @GadgetFreak
Marchen Maze High Score Save ROM Patches
Having done a few other Namco System 1 games, it makes sense to do another one using the same technique. As with Splatter House I don't have a board set running this game so the patches have been tested in Mame but should work 100% on the real boards. The patch requires no hardware changes...

Moon Cresta : @philmurr
Moon Cresta - High Score save
Following on from the Moon Cresta "attract mode in free play" mod I did a while ago, I've finally got round to the proper high score save mod. Moon Cresta already has a 5 place high score table and allows you to enter your initials. Problem is there isn't non-volatile RAM to save it, so power...

Mr.Do! : @philmurr
Mr Do! High Score Save
Inspired by @myPinballs work on recreating a Mr Do! PCB, I did a bit of work on my test ROM to help out with some sprite issues. This led me to have a look round the code... I know there are already high score save mods from JROK and Gadgetfreak, but both involve swapping out a (usually...

Mr.Do!'s Castle : @GadgetFreak
Mr.Do's Castle Screen Flip High Score Save Patch
I was originally going to put JRok's mod on this board but I wanted the high scores to survive test mode and to flip the inverted Universal screen. For the screen flip patch you will need to patch 3 roms and the high score save patch is only one of the roms. You can apply just the flip patch or...

Mr.Do!'s Wild Ride : @GadgetFreak
Mr.Do!'s Wild Ride High Score Save Patch
Another patch that you will need you to replace a ram chip, its the 8218 ram chip at H1 (next to the four program roms) with an NV version such as DS1220, M48Z02, U63716DC etc. The patches below are compatible with the Mame rom set DoWild. To reset the high score table enable freeze, ground...

Pac-Mania : @GadgetFreak
Namco Pacmania High Score Save Rom Patches
Got a faulty Pacmania the other week and have now finally got it working but was fed up with the high scores not being saved even though it has a 28C16 for the settings. So I set about adding High Score Saving to the US version. I am listing the patched bytes below which have to be made to the...

Pengo : @GadgetFreak
Pengo (Encrypted) High Score Save Patch
I was originally going to put JRok's mod on this board but when I went to his page I found he had only patched the unencrypted version which meant I would have to reprogram most of the roms and replace the Sega cpu. Being a bit of a purist I decided to come up with my own patch. Besides not...

Pleiads : @philmurr
Pleiads high score save / enhanced free play
The latest in my selection of high score save / enhanced free play mods is Pleiads. A fairly unpopular game, said to be the follow-up to Phoenix but I can't really tell any similarities other than the look of the graphics. Runs on almost identical hardware to Phoenix, and tons of the code is...

Pheonix : @philmurr
Phoenix High Score Save
Following on from my post about the Phoenix freeplay mod http://www.ukvac.com/forum/phoenix-enhanced-freeplay_topic352965.html, I've now managed to get the high score hardware working. I designed a plug-in replacement circuit board for Phoenix boards, replacing the existing RAM #4000-#43FF with...

Scramble : @philmurr
Scramble High Score save - *UPDATED*
I think Scramble is an awesome game (even though I'm not very good at it), and whilst it has a high score table, it lacks the ability to save it on power-down, and there isn't the facility to add initials to the high scores. So following on from my recent Scramble freeplay mod, I've now...

SnapJack : @GadgetFreak

Splatter House : @GadgetFreak
Namco Splatter House High Score Save Rom Patches
As I had done Pacmania/Galaga'88 I decided I probably needed to look at what seems to be the most sort after Namco System 1 game, Splatter House. As I don't have a board these patches have been done using Mame as a test bed but should work 100% on the real boards much the same as...

Star Force : @GadgetFreak + @edwoodjnr
Star Force High Score Save Patch * UPDATE *
Star Force High Score Save Patch ** UPDATE ** EdwoodJnr found an issue which I have now fixed, the game had flags embedded in the HS table to indicate which had the new high score but didn't reset them straight away so depending on when you turned the game off or started a new game, your...

Super Cobra : @philmurr
Konami Super Cobra High Score Save
This is my final high score save mod of the year (and I won't be doing any more for a while as I've some far more interesting projects on the go). So following on from the Super Cobra free play mod I posted a couple of weeks ago, here's the high score save (with initials) mod Just like...

Vanguard : @philmurr
Vanguard freeplay and high score save
Well I know I said I wasn't going to do any more high score mods for a while. That was until I picked up a Vanguard machine a couple of weeks ago, and just last week got talking to someone else who'd also just got one and we were both having a moan about the lack of a high score save function...
