Well, to make a long story short, I lost the Bay Route pcb because the battery went dead but was able to save the Tetris pcb from the same demise.
With these sega system 16b hitachi FD1094 A-12 custom chips they contain a battery which over time will die if you dont replace it. I found this out the hard way so if you have one of these boards, make sure to replace the battery asap!
I also learned after making this video that when you go to change these batteries out, make sure that you have constant power going to the chip because if you lose the power you board is dead.

The FD1094 is just a 68000 CPU with the game's decryption tables stored in SRAM kept by the battery. I have tried using a dead FD1094 in a Sega Genesis just for lulz and it would not work, go figure. They will not operate as normal 68000 CPUs with dead SRAM.

@hex1gon at the time, the problem was that most games which were popular at the time (i.e. Michael Jackson's Moonwalker) would be bootlegged, usually by copying the data on cheaper roms (which sometimes would have odd effects). and rather than lose money to the bootleg boards, they'll go ahead and place these suicide batteries to ensure that nothing will work.

I replaced the battery in my Moonwalker 'live' with the pcb running on an arcade PSU, that way it never lost power and survived the replacement.

I would clip on a pair of AA batteries before switching the cr2302 cell. don't worry the AA batteries wont kill anything. This is what I did to snes nes games and n64 save packs to not lose the content.

Hey Luke, you can replace that Hitachi FD1094 with a regular 68000 and burn some unencrypted ROMs to resurrect Bay Route..

@figment1988 12 лет назад

@segagenesis1989 do not grieve. at least this contra clone whose title was a play in words referencing a location which was in the headlines in the 80s (Bay Route = Beirut) has joined Golden Tee 2 in being one with the matrix.

@WickedClownNZ 12 лет назад

suicide batteries man, such a stupid bloody idea good to see tetris survived tho :)

@bitrate54 12 лет назад

Hey Luke. You can solder the new battery in parallel with the old battery before removing the old battery from the circuit. This way the circuit stays powered and you don't run the risk of losing data. With the cells wired in parallel, the voltage remains at 3.0V so the circuit will not be damaged.

@Helvetica_Scenario 12 лет назад

@JakalairVG pretty much. Luke mentioned "suicide battery" a couple of times during the vid. That's what they're called, basically. Once there is no power going to the board, decryption data is wiped, leaving the board useless, because it can't run anything from the encrypted roms. Your only option at this point is to burn new roms that aren't encrypted to "resurrect" the board.

Contact Chris at Sega Resurrection.

You may be able to revive Bay Route. There are decrypted ROMS available from Sega Resurrection.

つずけて、頑張って下さい。そのｾｶﾞｼｼﾃﾑ16ﾎﾞｰｱﾄﾞと諦めないでね。。。YOU WILL GET THE BOARD UP AND RUNNING AGAIN, KEEP TRYING YOUR BEST !! 右京　より

@NCXitlali 12 лет назад

@OilyTower, I know of a safer way to do it. Just solder some wire... and then buy one of those small clippie thingies (I wish i knew what tehy were called) and clip them on the battery wire. THere, no soldering with the battery :D

@Doomzdayxx 5 лет назад

Luke, I have a eSWAT pcb and the high scores do not save if I turn the power off on the cabinet. Is this normal or is there a battery on the pcb that I need to replace?

@AdrianDX 12 лет назад

@Nesveri Someone should start writing a show based on shows like E.R. and have Luke as the main character...Fixing video game harware in the nick of time, lol xP

@wrestletube1 12 лет назад

That version of Tetris was compressed into a medium chip and stuck into a Megadrive cart as well listing to the music that board gives out.

@segagenesis1989 12 лет назад

Rest in peace Bay Route. It was nice knowing you. *sniffles*

@Mulletsrokkify 12 лет назад

Not sure if you know dude, but there is some good info on arcadecollecting com slash dead slash dead.html.

@Helvetica_Scenario 12 лет назад

@JakalairVG they were made this way to keep bootleggers from copying the game.

The SEGA System 16's SUICIDE BATTERY

@Semikami 12 лет назад

This is like defusing a bomb or doing a surgery but more exciting. :D

@Hepglon 12 лет назад

@Nesveri Or bomb surgery for that matter. =D

@obsoletegeek 12 лет назад

All you need is a standard 68000 CPU and the patched ROMs.

@CRTcade 12 лет назад

Really cool to see the repair in live action. Nice work saving that Tetris board! I really hate it when certain boards incorporate suicide batteries. Hey, but if there's one person in the world who can get that Bay Route PCB up and running again, I would have to say it would be you, for sure. Awesome stuff as always!

Whenever Luke can't repair something, a little bit of me dies on the inside........

@JakalairVG 12 лет назад

Very interesting video. Any clue why they built it this way? Is it just that they never thought those things would be around for 20 years?

@NCXitlali 12 лет назад

DAMN! I am SOOO GLAD i never tried soldering batteries! I'm new at soldering. I am SOOO GLAD i watched this video! WOuld I run the same risk replacing SNES batteries????

@austenlangford 12 лет назад

im so sorry for your loss man that is truly sad to hear you couldn't save your motherboard but if anyone could have done it it would have been you so with that being said you done everything you possibly could have but the timing was all wrong great videos though and at least tetris is a win situation

@JakalairVG 12 лет назад

@castlevania78 Thank you so much for the information. I know very little about arcade boards, which is one of the reason I watch Luke, to learn.

@jaimeb.384 7 лет назад

How about an already dead board? Can they be resurrected?

@sirNemanjapro 12 лет назад

I just wanted to type that. I am surprised he hasn't done that in the first place. I mean its logical.

@JakalairVG 12 лет назад

@castlevania78 That is pretty ingenious. Copy Protection from another era.

@Helvetica_Scenario 12 лет назад

@JakalairVG no problem. I'm sure Luke can find someone to get him those new roms.

@MetalTiger88 12 лет назад

wow, that really was like defusing a bomb O_O nice job^^

@Mulletsrokkify 12 лет назад

@lukemorse1 Cool Luke. Glad to be of help bro!

@kenshiroonline 12 лет назад

i gain so much knowledge watching you!THX 4 that!!

@trev1976 11 лет назад

Can you repair system 32 boards too ?

@kakureru 12 лет назад

do not use rechargeable ;)

@ayuloveappears 12 лет назад

That's some old school DRM..

i have a wonder boy 3 how about if i change the battery when the board is on?

@thealternativej7994 7 лет назад

Yes, it has been done before with a gameboy cart, but be careful where you poke your soldering iron. Otherwise replace the battery with the board off or get a Sega Resurrection Kit.
