Most systems will use an accurate refresh rate calculated from display timing
N64, PS1, PC-Engine and Neo Geo Pocket use 50hz and 60hz until we determine how to calculate.
Adds a cheat editor to Tools->Cheats when a game is loaded.
The cheat editor should work for all systems except N64 and PS1: support for these will come later.
The code has currently only been tested for MS, MD and SFC but it is assumed all the other systems are also functioning; the code paths are the same.
Code format is standard patch codes in the format X:Y where X is a memory address and Y is a value to place there; most emulators also support this format.
You can use multiple codes in a single cheat by separating codes with a + sign.
Cheats that require memory comparisons are not currently supported, only replacements
Cheats are saved alongside the roms, eg "Game.sfc" will create "Game.cheats.bml".
This emulates the ZX Spectrum 48k and 128k models and should be fairly accurate
although imperfect; it is considered experimental for now. Save States are not
fully implemented, you may wish to avoid using them for this core.
No controller interface is currently exposed, meaning games must be played with
the keyboard at this time. It is planned to support the Kempston interface,
while supported by the underlying core, the UI interface for attaching expansion
port devices has not yet been implemented.
You must map a "Keyboard Capture" hotkey to allow ares to emulate the keyboard.
Ares maps most ZX Spectrum keys 1:1 with the same key on the host keyboard.
CAPS SHIFT is mapped to Left Shift, and Symbol shift is mapped to Left Control.
For special characters, it may be beneficial to look up the ZX Spectrum
keyboard layout. For the 48K it is necessary, as BASIC uses hot keys
rather than typed commands, for example, to load a game on the 48k,you must
type `J <symbol shift> PP` and then hit enter, which results in `LOAD ""`
being entered on the screen.
For the ZX Spectrum 128k, you can just use the Tape Loader menu option.
The emulator only implements support for raw WAV dumps right now; this is
because the TZX format is over-complicated, and I did wish to implement it at
this time.
There are many tools available for converting TZX to WAV, for all platforms,
so this isn't really seen as a blocking issue.
