FCE Ultra 0.98.17

About
I´ve made a bunch of additions to FCEU to help make TAS´s.

This version is 100% compatible with configs and movies from nitsuja´s 98.15.

This is still fairly untested so I can´t really make any guarantees. Post bugs on the forums or PM me and I´ll fix stuff when I have time

Thanks to nitsuja for the original source, Ike for shared-memory source, and Bisqwit´s forum for various suggestions.

Where to get it

Get the executable. Delete the ".foo" at the end, since 50webs doesn´t allow .exe´s. This is a windows executable and is compiled for a Pentium 2.

(Note: the source is for the previous version. I´ll upload newer source soon-ish). The source is also available. It´s too big to give as one file, so I split up the subdirectories: Main directory, /boards, /drivers, /fir, /input, /mappers, /palettes. Please note that I suck at makefiles (yeah I´m spoiled by Visual Studio projects), so I might have screwed something up. Also note that I had trouble adding memwatch.c and basicbot.c to the project, so I #included them in cheat.c instead.

Changes FCE Ultra 0.98.17

You can now run multiple instances of FCEU. (Previously the shared memory would screw them up, now only one copy of FCEU will use shared memory. Hopefully

BasicBot is now implemented.

Many enhancements to the speed of bot emulation. I think I killed the slowing bug, let me know if your FCEU is still running slow. On my computer this runs the same as the original FCEU.

Autofire offset will stay in sync when loading a save state while recording. Known bug: the 1st frame after the load, it could fail to fire when it should have. But it´s still better than having to readjust the offset all the time.

Added some commands to the NES menu so you don´t have to hotkey them.

Changes FCE Ultra 0.98.16

Added mappers/boards from the memory-mapper FCEU project.

Added a rewind feature. You must enable it manually every time because it´s a little experimental. All it does is save a state every few seconds to "rewindX.fcs" where X=0,1,2,3, which you can load by pressing the rewind hotkey (default "R", can be configured). (Note: If you´re running more than one instance of FCEU, only use in one FCEU at a time or you will get unpredictable results.)

Added a support for a hotkey to view the save slot you´re on. (No default key--pick it yourself in the configuration)

New input display. Press the input display button to cycle between 0, 1, 2, and 4 controllers displayed.

The "Run in Background" option now works correctly. Added an option to accept input while running in the background, which should be useful for making multi-game movies.

Compiled some parts with higher optimization settings, so you might get a small emulation speed boost.

Fixed a subtle bug (introduced by the shared memory code) that made FCEU crash in some cases eg. Bio Hazard (unl).

Added absolute value "abs" and "setcounter" to BasicBot. Also added "mem" which gives access to all memory locations 0-65535 (unlike "ram" which only could do 0-2047).

Memory watch can now access all memory locations 0-FFFE.

Memory watch is now throttle-friendly. It won´t slow you down when you increase the throttle.

A little more space for labels in the memory watch window.

Memory watch and BasicBot remember the last directory you used, even after closing FCEU.

Fixed the autofire not working 1st frame after loading a state while recording a movie.

Attempted to fix the read-only toggle glitch adelikat mentioned. Maybe it will work now?

More throttling speeds for people with crazy fast computers.

A few glitches no one will ever notice (unless you read the source code) have been fixed.

Features FCE Ultra 0.98.17

Shared memory--Outside programs can read information from the emulator.

Memory watch--Monitor up to 24 RAM variables at a time. Hex viewing has been added to this version. Use a prefix of ´!´ to watch a 2-byte (little-endian, which is what most NES games use) value, use ´x´ to view 1 byte in hex, and use ´X´ to view 2 bytes in hex. Save and load the list of addresses as a text file.

Autofire options--Change the pattern of the autofire under the Tools menu. You can also give the autofire an offset, to make the button presses land on the correct frames. Use the "Alternate A and B" option so that the B autofire pattern is opposite the A autofire pattern.

Stop movie--Automatically pause the movie on a certain frame, accessed on the replay movie dialog. (Sorry, can´t disable this once the movie started--but shouldn´t be a problem.) Useful if you need to fast-forward to a certain spot.

External input support--FCEU can read input from an external source. This will allow programmers to create bots. To enable this, click on the Tools...Use External Input menu. User input will be disabled while external input is enabled.


Features FCE Ultra 0.98.16

New mappers--Run more games than before! Paperboy 2 and various XXXX-in-1 games now work.

Rewind--A little unreliable, but very useful when watching movies!

External input support--FCEU can read input from an external source. This will allow programmers to create bots. To enable this, click on the Tools...Use External Input menu. User input will be disabled while external input is enabled.

BasicBot--A reasonably flexible, programmable bot. Now you can program instead of play.

Background input--FCEU can accept input while still in the background. Use this to make multi-game movies, for example.
