That's right. It is at least worth a shot.

If all else fails, I submit another question:

Instead of connecting the game genie via the cart slot, can the ROM chip from it be soldered directly to the Radica's ROM connections, and then wire a slot to that?

yeas but theres multiple chips

No offence MM007 but that's kind of like asking "why won't this very large square peg fit in this teeny tiny round hole"

If the Game Genie is incompatible with the Radica, which we won't know for sure until someone tries it, then ripping the chips out of it (the Game Genie) and soldering them onto the Radica won't work either!

Just hold fire until somene else completes Ben's Radica mod (has anyone else managed/dared to do this yet?) and gets chance to test it with a Game Genie. Ben can't do that because he doesn't have A Game Genie but if it works then fine, however I'll lay odds that it won't.

I was reffering to if we couldn't get all the pins for the cartridge slot, try soldering in the ROM directly. It isn't quite as far-fetched as it sounds.

But okay, we can wait.

There is a better method. My friend just informed me he has a cart that has a switch on it that changes the region of the system (sorta like the HoneyBee but better). I seemed to remember hearing about this cart too, but it came out so late that no one seems to have it, and probably not all that many were made. Anyway, I'll try and pump him for as much info on it as he has (since we're both in Japan away from most of our video games). Hopefully someone can find one and see how it's wired up, and we can make a region circuit for this thing and avoid the Game Genie altogether (assuming the Game Genie thing doesn't work). Worst-case, you'll have to wait until June so I can get this information first-hand.

Does Streets Of Rage 1, 2 & 3 work on the Radica + Cart Slot, i want a handheld genesis almost for this game

and comix zone as well

Comix Zone rocks! That's going to be one of the first games I try once I get around to modding my Radica, shortly followed by attempting to fit a 6 button pad which looks like it should be fairly easy to do.

Unidentified Assilant · Fri Dec 24, 2004 10:29 am

would it even be possible putting on a 6-button controller, I thought the controller was hardwired into the system? I wouldn't know cos I don't have a radica yet, for me, they are too dear for me to afford, how annoying.

Um, correct me if I'm wrong, but I'm pretty sure that the Gen3 didn't have Game Genie support. It seems to me that if the Radica is even more simplified than the Gen3 that it would also lack this support?

Red5 · Post by **Red5** » Fri Dec 24, 2004 11:43 am

That's what I keep trying to tell everyone Jaytee

Incidentally someone on the other thread asked if there were any differences between the USA and Euro (UK) versions of the Radica...

Looking at the photo on Lik-Sang, on what I'm guessing is the Japanese version, and at my UK unit: (numbers on Left are JAP, Right is the UK one. a ? means I can't see the numbers on Lik-Sang's photo)

Top (under A/V cables)
R????8-1 / RD1658-1
???C-1.1 / REV:B-1.3

Bottom (next to controller wires)
923-31601 / 923-31700
74065,NTSC-S / 74065,PAL-R

The part No. on the rom is also different, mine is labelled A305 with 2 Kanjii symbols underneath. For the most part the board looks identical, however there are some diffences around the area just underneath the DC jack - mine has an extra resistor, but there isn't a resistor soldered to to large capacitor (on the left) as there is on the Jap version so it's likely that mine is just an updated version. Sorry I don't have a camera before anyone asks

Concerning the z80, all sega genesis systems has a z80 or a chip as replacement of z80.
80% of the games are using z80 as a real CPU to control the sound chips so just imagine if there was no z80 (or z80 simulator).

If you remove the z80, i'm pretty sure that some games wont boot anyway...

For info, PuyoPuyo does use z80.

Red5: If you can post a pic of the ROM, I can tell you what the two kanji characters read. It's probably either Eikoku (England) or Oushuu (Europe) or something like that. I know the Japanese one simply says Japan and I think the USA one says Beikoku (America). Not that it's a huge deal, but if anyone's curious.

Hallo everyone! I'm new here - but am modding my Radica (about half done now...)

@Red5 - I own one of the original "Lik-Sang" JAP models and can tell you the letters on the stuff you mentioned...

UNDER THE VID CABLES

RD1658-1
REV C-1.1

NEXT TO CONTROLLER WIRES

923-31601
74065,NTSC-S

ON ROM

L09Y6(I)32M
(two kanji carachters - see ACSII art below) C4D0
L 04-07-14

ASCII ART OF KANJI

|E| (first Kanji is supposed to look like an "E" and the two side parts
are NOT separate, apparently means "SUN" according to a
"learn Kanji" website)

/T\ (second Kanji is supposed to look like a man with his arms and
legs wide open standing above a cross [NOT an X] - sorry for
the crappy ASCII ART! I don't know what the second one means...)

My best guess is that the Kanji is something like "Land of the Rising Sun" or words to that effect - signifying it's manufacture in Japan.

==EDIT #1==

Thanks @SgtBowhack for confirming my rather lame Kanji reading skills - still it was a good guess anyhow!

==EDIT #2==

If anyone wants to get one of these "Midget MegaDrives" in the U.K. - check my other post HERE

Sorry, didn't see this post. Those two characters are most likely "nihon" or Japan, as you said. The first character is sun (looks like a tall rectangular box with a line through it to make two smaller rectangles). The second character, which looks like a cross with two legs coming out of the cross' armpits, so to speak, and a line through the bottom of the cross is "hon" which can either mean "base" or "book" - in Nihon, it means base. Japan is the "base of the sun" (which is where the term Land of the Rising Sun came from).
I'd really like to know what the Euro version says (it might just say Nihon too, since the ROM is probably the exact same thing)
