1184
This score is for a CGL Frogger which I believe is the same as the Coleco but in a different case.
http://www.handheldmuseum.com/CGL/Frogger.htm
Do the CGL and Gakken Frogger games count in this section Rik?
Thanks, Neil. |

I'll put it under Gakken (CGL) for now... I'll have to play them side-by-side to make sure they are exactly the same... (Anyone else know for sure?) |

Thanks Rik .
All Coleco Froggers might not be exactly the same anyway. In the Museum you state "I'm told there's a game-play variation in (Coleco) Frogger as well".

The Gakken and Coleco have the same CPU, but not the same VFD tube. The Gakken is slightly larger, with a little more detail to the sprites. Don't know if that affects game play though.
They also share the joystick design, so no difference between metal strip or rubber pad sticks on this one. |

Do you have both of these opened? What are the exact numbers on your CPUs?
My Gakken Frogger is:
M58846-700P
My Coleco Frogger is:
M58846-701P
The number after the dash represents the program code on the ROM of the chip. Since this number is different, that implies that there is some difference in the code. It's not like software revisions either, M58846-702P could be a chip used in a car computer or something, it simply means the next ROM code loaded into the manufacturing process... (Obviously both versions of these ROMs were sent to manufacture by Konami at the same time, so that suggests they are similar, but there is a deliberate difference between them...)
My Coleco chip was made in 1982, and my Gakken chip was made in 1983, so they were definitely using both versions concurrently...
I know there are differences in Coleco Froggers too, so it's possible there are 700P chips in some Coleco Froggers... I have another one I can open, so I'll check that one out as well...
Comparing the VFD display itself, mine are both exactly the same size. If you can see the back of your VFDs:
My Coleco is CP5090
My Gakken is CP5084
This is printed inside the glass, and on a sticker on the back of the display.
The glass and the sprites are the same size, but they are not 100% identical. One really obvious difference is my Gakken VFD has what looks like a dying frog at the very beginning (left side) of the 1st and 3rd rows (frogs on logs) and the end of the 2nd and 4th rows (frogs on turtles). I assume you die in either version if you let the logs/turtles carry you off the edge of the screen, but the VFD actually shows it on the Gakken one. (I'm looking at two games that don't work, so I can't play test them...) The vehicles look different between them too...
Ultimately, differences in the VFD display won't affect scoring as it really doesn't affect the game play... It's the difference in the code on the CPU I'd be concerned with. It'd be nice if we could find a quick, easy way to identify any difference without having to open the game...

Does it have a Demo mode. Maybe you can check how they run side by side if you turn them on at the same time. I might have the idea that the Coleco allows you to hop on logs at the far end of the display, while you are already dead on the Gakken (the falling frog symbol). |

Can you see that from the top? Most of the more advanced panels are soldered on 2 sides. I only have my mint Frogger here, and I'm not going to open that one . |

No, you have to lift up the VFD a little. The Frogger ones are only attached on one side, so you can do that easily, but it's not necessary. The VFDs aren't different enough that it's a concern. (You have to do that to see the CPU in Coleco ones though as the chip is under the VFD...)
I'll have to find my Gakken Frogger so I can play them both side-by-side. I have at least two Coleco Froggers that I can open and inspect as well (and play them all at the same time)... Maybe we can figure all this out.

I found some differences.
Gakken has sound mute switch
Coleco has reset button
Coleco has turtles that disappear (did not see that yet on my Gakken, maybe in later levels). The Gakken version has bigger gaps between logs at certain moments. Do you die at the far left/right while jumping on the water with the Coleco? |

Here is my score for the frogger. 6378 level 2. That little one required all my attention pass 5K. Most of the time you get only one log to park the frog at he top and its moving damn fast. Oh Billy my friend, tell your wife she has my deepest respect but all good things must come to an end. Take care bro.
