2 on 2 Open Ice Challenge

The volume for this game is TOO LOW!

When the game is running, hit F2 to get to the internal service menu. Hit F2 again to "close" the service switch so that you won't get stuck in the menu. Now, navigate to the "Volume Adjust" option (following the directions provided) and adjust the volume. It's best to keep the volume no more than 80-90% filled as it might cause your sound to be overdriven and crackle. When adjusted, simply exit the menu.

720 Degrees

This game uses a spinner control, right?

The original controller for 720 Degrees was a joystick that was hardware-limited to only travel along the outermost edges in a circle. The internal mechanism for reading this control was similar to a spinner except that it had the additional benefit of knowing which direction the joystick was pointing. Because this knowledge is an important aspect of the game, the current emulation of the controller maps an analog joystick to the underlying controls instead of a spinner.

Double Dragon

Gameplay is choppy at times, but I have enough CPU power?

Although the FPS counter shows 100% speed for these games, they may appear choppy. This is true to the original — even the original hardware of these games struggled with them and therefore the choppiness is actually accurate emulation of these games. You may be able to get rid of it in some cases by using the -cheat parameter, hitting the tilde key and browsing the on screen menu until you find "CPU overclocking". This will run the emulated CPU faster which may or may not fix it. It may also cause the emulation to have errors, so don't bug people if overclocking screws up a game.

If you are having trouble controlling vehicle or the brake is always on, calibration must be done!

First off, Delete any .NV (NVRAM) file for this game contained in your NVRAM directory, called harddriv.nv or racedriv.nv or the same as the setname you intend to use. You need to understand how the controls are mapped in MAME. It's not very intuitive, so pay attention:

• Steering wheel: Player 1 Paddle control, by default maps to the mouse and the left/right arrow keys
• Gas pedal: Pedal 1 control, by default maps to the Left Control key. Pressing the key will quickly depress the analog control; releasing the key will release it.
• Brake pedal: Pedal 2 control, by default maps to the Left Alt key. Operates the same way as the gas pedal.
• Clutch pedal: Pedal 3 control, by default maps to the Space key. Operates the same way as the gas and brake pedals.
• Analog Shifter: (found in the non-compact versions only) Maps to the Player 2 analog joystick X/Y axes, which are mapped by default to the keys R, F, D, G.
• Digital Shifter: (found in the compact versions only) Maps to Player 1 buttons 2, 3, 4 and 5. First gear is button 2 (default: Left Alt). Second gear is button 3 (default: Space). Third gear is button 4 (default: Left Shift). Fourth gear is button 5 (default: Z key).
• Key: Maps to Player 1 start button (default: 1 key).
• Abort: Maps to Player 2 start button (default: 2 key).

Finally, here is a step-by-step tour through the calibration process. Note that even if you have an analog control connected to any of the analog controls in the game, it is much easier to do calibration with the keyboard.

1. Take your hands and feet off all controls then turn key. Make absolutely sure you haven't touched any of the controls up to this point, then press the 1 key.
2. Turn wheel counterclockwise as far as it will go then turn key. At this point, press and hold the Left key for about 5 seconds. After 5 seconds, press the 1 key while still holding down the left arrow. It should say New min 256.
3. Turn wheel clockwise as far as it will go then turn key. At this point, press and hold the Right key for about 10 seconds. After 10 seconds, press the 1 key while still holding down the right arrow. It should say Max 3840.
4. Put transmission in first then turn key and release. Since first gear is in the upper-left corner, press and hold the D and R keys for 5 seconds. After 5 seconds, press the 1 key while still holding down the D and R keys.
5. Put transmission in fourth then turn key again. Since fourth gear is in the lower-right corner, press and hold the F and G keys for 10 seconds. After 10 seconds, press the 1 key while still holding down the F and G keys.
6. Move seat full forward then turn key and release. Since the seat feedback isn't implemented in the MAME driver, just go ahead and press the 1 key here.
7. Move fully back and to side then turn key again. Just press the 1 key here again to move on.
8. Take your foot off the brake turn key to abort. Now this is the tricky part. When you see this screen do nothing. Wait for a couple of seconds until it displays New max 4064. Do NOT press the 1 key prematurely here or you will screw up the calibration!
9. Now step on brake firmly and release. Do this by pressing and holding the Left Alt key for 3 seconds, and then letting go. If all is well, it should display Range 4064 and move on to the game.

There, now that wasn't so hard, was it?

Player's Edge Plus (Set038) Set Chip

peset038

This is not a game. It's a one screen utility program which is meant to be used after you already successfully put a new game in your machine.

Lets say you have 'pepp0516' installed and you go through the setup. In a real machine, you may want to add a bill validator. The only way to do that is to un-socket the 'pepp0516' chip and put in the 'peset038' chip and then reboot the machine. Then this chip's program runs and you set the options and put the 'pepp0516' chip back in.

The only way to simulate this is to fire up the 'pepp0516' game and set it up. Then exit the game and copy the pepp0516.nv file to peset038.nv, and then run the 'peset038' program. This is because they have to have the same eeprom and cmos data in memory to work. When you are done with the peset038 program, you copy the peset038.nv file back over the pepp0516.nv

How do I calibrate the guns? Can I use a real light gun?

The game will automatically ask you to calibrate the guns when you start the game for the first time. Simply put, use your mouse or keyboard to "target" the top left corner when the game asks so. There aren't any visual cues to help this, so you'll have to go by the numerical coordinates that are visible on the screen. The numbers you see are in a simple 8-bit scale going from 0 to 255. To "target" the top left corner, keep moving your mouse until you get P1 X and P1 Y as near to 0 as possible. The middle is located at about 127, 127, and the bottom right corner as close to 255 as possible. Repeat the process for the second player. As for the light gun, the short answer is no. A longer answer is that the game didn't actually have a light gun — it had analog joysticks mounted as guns, and emulating them with a proper light gun is not viable. Try to use mouse control with this game.

Terminator 2

How do I calibrate the guns? Can I use a real light gun?

The game will automatically ask you to calibrate the guns when you start the game for the first time. Simply put, use your mouse or keyboard to "target" the top left corner when the game asks so. There aren't any visual cues to help this, so you'll have to go by the numerical coordinates that are visible on the screen. The numbers you see are in a simple 8-bit scale going from 0 to 255. To "target" the top left corner, keep moving your mouse until you get P1 X and P1 Y as near to 0 as possible. The middle is located at about 127, 127, and the bottom right corner as close to 255 as possible. Repeat the process for the second player. As for the light gun, the short answer is no. A longer answer is that the game didn't actually have a light gun — it had analog joysticks mounted as guns, and emulating them with a proper light gun is not viable. Try to use mouse control with this game.

Water Match

This game is impossible to control. What do I do to play this?

The instructions are on the game's bezel. The game involves waggling the two joysticks around like an idiot. Here's what you have to do: For freestyle and backstroke swimming, move the two joysticks up and down in opposition to each other (when one is up, the other must be down). For butterfly, turn the joysticks "outward" — left clockwise, right counterclockwise. For breaststroke, turn them "inward" (left counterclockwise, right clockwise). (You need to use the start button to dive into the pool and the turn button to turn around.) For rowing the rowboat, move the joysticks up and down in sync (both up, both down, both up, etc.). For rowing the canoe, move the joysticks up and down independently: the left one if the canoe is veering to the left or the right one if the canoe is veering to the right. (One of the buttons is involved as well, but it's too hard to make out in the photo.) You have to press one of the buttons (not sure which one) to right your canoe when it capsizes.
