Stella v3.7.1 changelog:

3.7 to 3.7.1: (June 8, 2012) * Note: because of TIA changes, the state file format has changed again, and old state files will not work with this release. * Improved TIA emulation with ROMs that have too few or too many scanlines; the output is now more accurate compared to a real TV. Special thanks to Omegamatrix of AtariAge for test ROMs in this area. * Modified hotkey for "Change console palette" (Control-f) to also change the display properties of the TIA. This allows you to switch between NTSC/PAL/SECAM (and variant) modes dynamically. Related to this, added Shift-Control-f key to step backwards through the available modes. * Added '64in1' and '128in1' multicart bankswitching schemes, which work the same as the 2in1/4in1/etc ones (Control-r switches to each consecutive game in the ROM). * Fixed several bugs in DPC+ bankswitching scheme, including ability to load and save state files. As well, ROMs now work correctly after console format autodetection. * Fixed bugs in handling relative filenames on the commandline, introduced in the last release. The new functionality should be much more robust.
