Amiga Forever Essentials for Chrome aims
to both support the development of
third-party emulation apps and to make it
easier for users to enjoy such apps. In
order to achieve this goal, legal and official ROM and OS files
licensed for use in Chrome are made
available, with a shared access mechanism
for developers.
A self-describing JSON index file
("index.json") lists the available files and
their properties. All items are inside the
"shared" directory under the Amiga Forever
Essentials
"aemohkgcfhdkjpoonndfpaikgbpgcogm"
Application ID namespace.
Additional information about the content
of the JSON index:
- Amiga Forever Essentials ROM files
are 512 KB, and may be XOR-encoded as illustrated in
memory.c of the original
UAE source code (October 1997 and
later versions), in which case the
"keyFile" property references the key
- The compatibility of each ROM and OS
file is described using one or more
RetroPlatform system tags, of which
currently only "a-500" is guaranteed to
be supported for the Chrome environment
- Different RetroPlatform disk image
file types may be present, but only the
"adf" disk image type is currently
guaranteed to be included in Amiga
Forever Essentials for Chrome
- The above means that it is safe to
rely on the presence of ROMs for the
"a-500" model and "adf" disk images
- ROMs and disk images have a "name"
property for listing in drop-down menus
and similar user interface options
- Bootable disk images have the
"bootable" property set
- The EULA software license file is
referenced by the "eula" property and is
currently guaranteed to be present as
"text/plain" ("type" property) and/or
"text/html"
