Usage Guide

Getting Games

To get a game click the "FreeDLC" button and check which games are available right now.

Playing Online

To Challange someone double click their name on the list of players or click their name and then the "Challange" button.
Choose the game you want to challange someone to from the list and click Challange. If they accept you'll be taken to the host panel. 2a. If it says "Romname or game mismatch" that means the other person does not have the game you're trying to challange them to. OR they have a different rom than the one you are using. Both players must have the identical rom for netplay to work. I suggest always getting them from the freeDLC panel.
When they accept you will be taken to the host panel.

Here you'll be given a couple of options. 3a. "Delay" is how much delay you should have between you and the other person. The higher the ping the higher the delay required to play. If you get choppy gameplay or very low FPS, set the Delay Higher. Usually the "Suggest" button will do a fair job at estimating how much the delay should be. 3b. You can also choose the game Region, some games require a specific region to work because they were never released outside of that Region. For example most of the Guilty Gear games will not work in the USA region since they were never released in the USA. Other games like (Marvel Vs Capcom 2 or (Naomi)Capvom Vs SNK 2 will change the in-game language depending on which region you choose. If you get an error saying "Couldn't ping the player" that means they are being blocked by their Firewall. Ether Click the big green button in Options to add windows firewall settings or have them allow BEAR and nulldc through whatever firewall software they are using.

Spectating Others

To Spectate someone double click their name on the list of players or click their name and then the "Challange" button.
Spectating will start from the begining of the player's session.
You can fastforward by pressing w.e button you have bound to "Right"(Naomi) or D-pad Right(Dreamcast Controller) or Stick Right(Dreamcast Arcade Stick) 3a. If you have software that limits FPS (If you set the FPS limit in Nvidia for example) it will not go faster than w.e you have set in it. For fast-forward to work you need to have an uncapped frame-rate.

Playing Offline

Click "Play Offline" and Choose your game from the list. You can also simulate delay to practise for online while while still being offline.

A: Press ABXY + Start to go into the dreamcast menu and then go to memory card and delete w.e games you don't want to play. BEAR comes with an almost full VMU(Memory card) with lot of saves for fighting games mostly, you can get rid of any you don't want to use.

A: Just rebind the buttons (See controls above) and instead of clicking a controller, click a keyboard button.

Q: The game seems kinda stuttery not sure how to describe it, it's not lagging it just feels stuttery but the FPS is fine.
A: Try turning on Vsync that works better on some systems. In NullDC got to options->powervr->vsync and make sure it's checked. That should lead to a more consistent experiance for your system.

Q: The player name overlay is in the way of my game.
A: In the OPTIONS part in BEAR there are 4 type of overlays to choose from and off. It can be up/down and be full(CVS2 Style background and names) or minimalistic(just player names nothing fancy) or off.
