Frogger
Frogger is a 1- or 2-player game in which players move their frog from the bottom to the top of the screen. This is achieved by overcoming a number of hazards without getting run over or drowned.
The first half of the screen is a bi-directional flow of traffic including busses, cars and racecars. Players must avoid these vehicles. Frogs can move safely with the flow of traffic to make their way to the second half of the screen, which consists of a river with fast moving logs and sinkable turtles. Frogs must hop on the backs of the logs and the turtles to get to the home base at the top of the screen. At random times throughout the game play, a lady frog will appear on a log. Bonus points are scored if the frog successfully hops on the back of the lady frog and escorts her safely home. A fly will also appear randomly in a home base. Bonus points can be scored if the frog hops in the home base when the fly is present. Sinking turtles also swiftly move across the river with the logs. If a frog is unsuccessful in hopping on a turtle's back, the frog will sink and drown. Crocodiles, snakes, and otters also roam the moving river waiting to eat frogs on their way up to the home base. Players can hop on their back (except the snake, whose touch is deadly), but they must avoid their open mouths. The frog must be lined up perfectly to enter one of the 5 home bases. Players must maneuver the frogs to their home base within the allotted time (60 beats on the timer).
The frog can move vertically or horizontally by maneuvering the joystick. Players must maneuver the frog swiftly and precisely without getting run over, drowned, or eaten by the creatures that roam the flowing river. Avoiding traffic, deadly snakes, otters, crocodiles, and the treacherous diving turtles make game action stimulating in Frogger.

Tips on Frogger
* When you start the game, your frog will start at the bottom of the screen. You will have 60 seconds to move your frog up 10 spaces and successfully put it in their home. If you are successful, then you will try to put a frog in the next home and so on until you fill up all five homes with frogs. When you do this, you progress to the next level.
* Note the traffic flow of the 2 parts. The cars travel on the roadway from left to right while the logs, turtles, crocodiles, etc. travel on the water lanes in the following direction :
a) Lanes #1, #3, and #5 go from right to left.
b) Lanes #2 and #4 go from left to right.
* First, you must cross the highway. You will become road kill if a vehicle hits you or you hit a vehicle. Try to find 'lanes' in between the vehicles. You must plan for gaps to form in the first three lanes so you don't become trapped. The vehicles in the first three lanes move slowly enough that you can jump side to side with reasonable safety.
* Lane #4 is the dangerous lane. Depending on how much time you are taking, the cars may pick up speed even though it shows slow on the chart. Keep this in mind when you are moving your frog.
* At level 3, a snake will either be in the median or on the log in water lane #3. The snake is deadly to your frog and you cannot hop over it.
* The turtles are pretty easy to navigate over in water lanes #1 and #4. Be wary of the diving turtles and only use them as a quick bypass to a more solid footing. If your frog is on a diving turtle when it dives, your frog will drown.
* Again, time your jumps to coincide with the logs and turtles to ensure you will always have a solid footing to jump to. As the levels progress, you will have less things you can jump to.
* You can jump on the backs of the crocodiles and otters. Just don't get near their mouths or they are apt to turn your frog into a meal.
* You may see a purple lady frog hopping around on a log in water lane #2. Just cross over her to give her a piggyback ride to your home and get an extra 200 points.
* Watch out for the snakes, they sometimes like to ride on the logs. If you see a snake on a log, jump back to solid footing.
* Your frog cannot 'wrap-around' the screen so make sure you bail off before that footing disappears off the edge of the screen or your frog will come out the other side in a squished condition.
* By that same token, if you have the time and necessary footing, you can hold out until the fly appears in your home before you settle your frog in. That's another 200 points.
* Try to fill in the two end homes before going for the middle. The hardest home to get into is the left-hand one (home #1) since everything in water lane #5 goes from right to left. This means you may have to bounce back to water lane #4 so you can get a good shot at your home.
* Speaking of getting your frogs into their homes, you must hit exact center or your frog will die. Also, keep in mind that crocodiles like to randomly appear in your home. Make sure that your home is clear before trying to settle your frog down into it.
* Again, if you waste too much time, the things on the river will move quicker so you will have to adjust your strategy accordingly.
* When the game is playing in attract mode, you can control the frog. When the frog reaches water lane #4, you can control the frog's movements until you move either up or down.
* If you jump into your home at the same time the crocodile is leaving your home, you will be credited with making to your home but you will still lose a frog in the process.
* You can dangle your frog from the left side of the turtles but not the right side.
* Your side-to-side movements in water lane #5 may be slow and sluggish.
* The lady frog will sometimes be invisible. In this case, the only time you know she's there is when you jump on her. She will then ride on your back to your home.

Bugs:
- Clone froggrmc: After starting a game, the sound cuts off. Not in 36 final. Doesn't happen on the other sets of Frogger. Karasu (ID 00100)
WIP:
- 0.137: Fixed rom names in clone Frogger (Sega set 2).
- 0.134u3: Derrick Renaud fixed rom names in clones Frogger (Sega set 1/2).
- 0.133u1: Renamed (frogseg1) to (froggers1), (frogseg2) to (froggers2) and (froggrmc) to (froggermc).
- 0.130u2: Couriersud fixed autosave does not work correctly in clones Frog (Galaxian hardware) and Frogger (Moon Cresta hardware).
- 0.126u1: Couriersud fixed background doesn't rotate in cocktail mode.
- 9th July 2008: Mr. Do - Added cocktail instruction cards to Frogger, thanks to a loan from Gene at Vintage Arcade. Re-did the Frogger upright bezel. The scan that I had (from Vintage Arcade) was kind of dirty, but I was able to use it, along with a control panel overlay, to recreate the bezel. So on this one, the gray pattern background doesn't exactly match the true upright bezel, but it's a lot better than before, and all other parts are correct.
- 0.124u1: Added Discrete sound. Changed visible area to 224x768, palettesize to 32 colors and description of clone 'Frogger (Falcon bootleg)' to 'Frog (Falcon bootleg)'.
- 0.113u2: Changed VSync to 60.606061 Hz.
- 9th August 2006: Mr. Do - Thanks to Trigg, I realized that one game can have more than one view, including more than one type of artwork in the file. (Well, Aaron explained it, but I guess it went woosh over my head the first time). This will be good for a great deal of games. First one will be Frogger.
- 4th August 2006: Mr. Do - Added Frogger bezel, Addy throws in yesterday.
- 0.99u8: Pierpaolo Prazzoli added clone Frogger (Falcon bootleg). Added Frogger color prom to clones Frog and Frog (Galaxian hardware).

- 0.53: Changed palettesize from 100 to 99 colors.
- 0.37b16: Fixed gfx1 rom loading. Changed VSync to 60.606060Hz and palettesize from 32 to 100 colors.
- 5th March 1999: Aaron Giles has fixed more drivers to work with rotation handling (galaga, frogger, burger time and their clones).
- 0.36b10: Added Frogger (Konami 1981). Changed 'Frogger (set 1)' to clone '(Sega set 2)' and clone '(set 2)' to '(Sega set 1)'. Renamed (frogger) to (frogseg2), (frogsega) to (frogseg1) and (frogger2) to (froggrmc).
- 0.33b7: Added color prom pr-91.6l. Changed description to 'Frogger (set 1)' and clones '(alternate version)' to '(set 2)' and '(alternate version #2)' to '(modified Moon Cresta hardware)'.
- 0.31: Nicola Salmoria added clone Frogger (alternate version #2). Gerald Vanderick added accurate colors to Frogger.
- 0.30: Frank Palazzolo fixed music tempo in Frogger.
- 0.26a: Frogger doesn't have garbled chars anymore.
- 0.22: Some fixes to sprite priority in Frogger. Added high score saving to Frogger.
- 0.20: Frogger music tempo bring back to original value. Fast but flawless!
- 0.19: Some changes to music tempo of Frogger.
- 0.15: Added clone Frogger (alternate version) ("frogsega"), smaller and with different help, but still (C) Sega 1981. Sound support in Frogger [Nicola Salmoria]. All these require -frameskip 1 on my 486/100. I have no idea how accurate the tempo and pitch is. If you can compare it with a real machine, please let me know what's wrong. Added audio CPU roms 608, 609 and 610 from clone frogsega to frogger.
- 0.13: Fixed clone Frog "froggers" [Nicola Salmoria]: I broke it while adding sound to Scramble. It now also uses the correct palette. Yes, I know that it is completely different from the real Frogger. This is a bootleg version, remember.
- 0.08: Mirko Buffoni added better colors to Frogger. Colors for Frogger derived from SPARCADE by Dave Spicer.
- 0.06: Nicola Salmoria added Frogger (Sega 1981) and clone Frog (bootleg, version running on a Scramble board). Game is playable with wrong colors and no sound. Control: Arrows = Move around. Note: Frogger has one 32 bytes palette PROM, connected with resistors to the RGB output. Additionally, there is a bit which is 1 in the upper half of the display (136 lines? I'm not sure of the exact value); it is connected to blue through a 470 ohm resistor. It is used to make the river blue instead of black.
- 12th February 1992: Dumped Frogger (Sega set 2).
