Everyone, check out the box that MikeA made me:



Thanks to his enabling, I can now fit 42 SEGA carts and 21 EA carts into a single box.

Outstanding.
Bonus points for the TMNT burn.

So turns out my issue with Ristar was a bent pin on the console cartridge connector.  Back when I first started, I was using rig wire that was too thick and that was that.  Anyway, I used a needle to bend the pin back out and have regressed to the late 80s repair of permanently leaving a Game Genie installed.

Working on roping in another sucker, spent the afternoon popping chips.

Finished up a couple of carts for a forum member.  The juxtaposition of bootlegs of two of the most coveted games and his labels is amusing.

If any of you want into bootleg Genesis games, speak up soon.  At this point Iím going to have to dump another $100 in boards and EPROMs to keep it going much longer.  Iím back to popping chips off old boards and damn it sucks.



I hope to never make a Phantasy Star 4 or Sonic Complete ever again.  Ever.

Okay, finished these up.  Going to a guy that didnít grow up with a Genesis, so the challenge was to get a definitive collection into 12 cartridges.  Figured Iíd share the list but Iím not making any changes so keep your negative feedback to yourself.   ;D



I cheated a lot with that 10 in 1 cartridge, using a Brazilian Tec Toy rom.  It has Golden Axe, Revenge of Shinobi, Sonic 1, Streets of Rage 1, etc.  Nice sampling of early SEGA.

Contra Hard Corps - patched back with the life bars so you have a chance.

Crusader of Centy because nobody has ever played it and it sells for $300-400 loose.

Mortal Kombat 2 Unlimited with color patch - looks good, plays good, you can be the boss, etc.

Phantasy Star IV because nobody could afford it in the 90s and itís still ~$90

Sonic Complete - this is Sonic 3 and Sonic and Kunckles combined and tweaked.  Excellent rom hack.

Sonic Spinball

Streets of Rage 2 - probably the best fight and go right made and Iíve played through damn near all of them.

Thunder Force IV - very nice presentation and sells for ~$75.  A good choice if youíre only getting one SHMUP.  I give it a slight edge over MUSHA.

Vectorman 2

Xeno Crisis - homebrew so good you wonít believe itís on Genesis.  Iím curious to see how he does with it because it is ---smurfing--- hard.

Road Rash 2 - have to break the aesthetic with one EA cartridge and this is an excellent choice.

Its a great sampling of games. When he asks for more carts you can make him Shinobi 3 and or SoR3.

Never owned one of these in my youth... A care package arrived today from PBJ, and boy did he hook it up! As Malenko said, a nice sampling of games was included!

Now... It's time to blow ---steaming pile of meadow muffin--- up.


Many thanks, Jim! This ---steaming pile of meadow muffin---'s awesome! :cheers:

I helped curate the list via text messages with Jimmers, guess he left Earthworm Jim 2 off the make list and Contra must have beat out GunStar Heroes.
I made that Vectorman 2 label just for you.

I have another spare Model 1 Genny, wonder who we can rope in next?

NHL 94 is legit tho, and the 2022 hack is ever gooderer.

He should have sent you Mutant League Hockey then , you can just play it as an overhead beatem up instead of hockey.

Aw, heís actually playing games instead of turning one on after another.  I sent you an NHL 94, bro.

 :angry:

Give it a shot.  Games take 10 minutes and itís actually very good.  At least youíll have it in the cartridge larder if a friend visits and wants to play it.

We need to decide how many carts we want so I can buy more EPROMs.  Chop, chop.

Nobody is allowed to visit my domicile. Nobody. Single player all the way baby!

I'll look through some lists for some other stuff. Homebrews definitely interest me.

You're doing good stuff pbj.

Set yourself up as a kindof "speakeasy" for homebrew carts.

Making some more carts for my slave driver...



One recent revelation has been that if a 2MB chip fails when it's around 1MB burnt... that means a 256Kb or 512Kb ROM will burn and play fine.  The chip will fail verification but the Genesis don't care.

So that's how Nephasth has MUSHA.  I will be testing this theory further on a chip failing around 400Kb with a copy of Rambo 3 (256Kb).  Rambo 3 is oddly a very good game that nobody owned except me back in the day.  Sells kinda high on the resale market from what I've seen.  My dusty brain recalls some invincibility trick I will have to refresh myself on, but it was still fun to play through.

I also had a 4MB chip with legs that crumbled into dust when I was messing with it.  I was able to scrape back the sides of the chip and get a metal nub exposed and solder some kynar wire to it.  It miraculously works, so now I've got a copy of Mortal Kombat 2 Unlimited with Kintaro Action Grip.

 :cheers:

This one Iím kind of proud of, felt clever for the first time in a long time.  Couldnít get Water Margin to boot no matter what I did to the No Intro rom.  So I busted out my $30 Genesis flasher that works with the cheap Chinese flash PCBs.  Well, they used to be cheap - $2-3 each.  I should have bought 500 of them and spared myself future misery.  Now theyíre $10.  Anyway, the flasher can also dump cartridges, so I dumped my bootleg of Water Margin I bought from Malaysia.  Malenko made that replacement label art because it came with garbage originally.



ROM still wouldnít boot, even though it was a clean dump.  So I put all my EPROMs in my UV easy bake oven and scratched my head for awhile.

Then I go, you know what, letís check the header.  Sure enough, it was full of scrambled garbage.  So was the no intro rom.  Iím actually unsure how my bootleg cart even boots.  Maybe itís fine on the chip but dumps weird.  Who knows, but my dump matched their dump.  Same scrambling.

I copied over the information from the Streets of Rage 2 header andÖ.




They should have called this game Swamp Bandits but at least weíre in business.

Got 50 repro pcbs in today.  Means I can crank up the pace.  I need to print a couple of labels but got seven soldered up and assembled in an hour.

More chips, more pcbs, more sports games shellsÖ.

Lots of home brew and rom patches in this pile.







SF2 using the Z80 for audio.  Arkagis Revolution doing sprite rotation.  No idea how they pulled that off.


I also made myself a Rambo 3.  Used to actually own this.  A very odd, very early Genesis game.  I remember screenshots in the print ads not matching up to the actual game.  The enemy sprites donít do that flicker thing so when you get a bunch of enemies on screen it slows to a crawl.  I counted ten enemies at one point.

Very unfortunate ending in hindsight.

It was an astute person who penned the "Graveyard of Empires" moniker.

Crazy how many of those games I have never heard of.

But those Blockbuster labels bring back some memories!
