5 | 1. FCE Ultra uses SVGAlib, so you'll obviously need to have it |
6 | installed. |
7 | |
8 | 2. Be careful when using the non-VGA video modes(such as 640x480). |
9 | SVGAlib doesn't always handle virtual terminal switching well when |
10 | one of these modes is being used. Also, since FCE Ultra enables a |
11 | a linear frame buffer for these modes, heed this warning from |
12 | the SVGAlib documentation: |
13 | |
14 | Furthermore, some cards (Cirrus) just enable this buffer |
15 | at a fixed hardware address. For Cirrus it is mapped at |
16 | 14MB so you should never used it if you have more than |
17 | 14MB of memory (But how does an application know?). The |
18 | Mach32 support for this is smarter. It makes this feature |
19 | only available when it is safe to be used. |
20 | |
21 | 3. FCE Ultra must be run as root in order to get access to the |
22 | VGA hardware. SVGAlib will drop root privileges if you are running |
23 | the program as a normal user and the suid root bit is set and the |
24 | executable is owned by root. Example: |
25 | chown root fceu ; chmod 4755 fceu |
26 | Make sure you have the latest stable release of SVGAlib, though. |
27 | |
28 | 4. FCE Ultra will save all data(state saves/screen snapshots) in |
29 | ~/.fceultra, so make sure your "HOME" environment variable is set |
30 | correctly. |
31 | |
32 | If you believe FCE Ultra is too slow, you can try the following: |
33 | * Kill some of the other processes. |
34 | * Disable sound emulation. |
35 | * Raise the priority of FCE Ultra with the 'nice' command. |
36 | Ex: nice -n -20 ./fceu |
