games have defaults that look good enough. Some games will cut off a few pixel lines at the top and bottom - but they will
|
||||
still be perfectly playalbe. Such is life with only 192 vertical pixels to play with on the DS!
|
||||
|
||||
Recent versions of the emulator have a magnifying glass icon that will zoom and center the display to 1:1 of the actual 7800 output.
|
||||
This will crop some pixels off the sides and top/bottom but is useful to temporarily zoom up to enter things like high scores
|

where the text may be hard to read when shrunk down.
|

|

Frame Skipping can be OFF (show all frames), Moderate (Show 3/4 frames) or Agressive (only show 1/2 frames). The latter is
|

only really needed for the DS-Lite/Phat where the faster DSi CPU isn't available.

V4.5b : 05-May-2024 by wavemotion-dave
|
||||
* Each game that utilizes a High Score Cart (HSC) gets its own 2K .hsc file
|
||||
* Sanity checks added so that carts marked as 'NORMAL' (or selected as such) but are larger than 48K will not corrupt memory.
|
||||
* New magnifying glass icon to ZOOM (and center) the display 1:1 with real 7800 output. This will crop on a DS/DSi since it only has 256x192 but very useful to toggle the 1:1 zoom for High Score Entries, etc.
|
||||
* Starting to lay groundwork support for .a78 V4 headers...
|
||||
|
||||
V4.5 : 18-Nov-2022 by wavemotion-dave
|
||||
* SNES2Atari adaptor supported.
|
||||
* Improved display output to smooth over the fonts a bit.
