User guide

DSPEC.INI

• Drop DSPEC.INI into the root of your filesystem, along with DSPEC.
• You can edit this file to change the default control scheme and files paths.

Redefine controls within DSPEC

• Go into the settings and use the icon that looks like arrow keys.
• When editing controls withing DSPEC you can optionally save them.
• Doing so will create a file that pairs with the currently loaded ROM.
• If for example you have chuckie.sna loaded, and save the control scheme, the control file chuckie.ini will be created.
• When loading a ROM, if the default control file exists, it will be loaded and used.

Rom specific control files

• These can be created within DSPEC or manually created and dropped into the appropriate configurfation folder.
• They are only text files, so can be edited or viewed from notepad or similar.

Loading ROMs

• The load icon has been removed.
• Double tap the list entry to load it.
