2. Brief overview of MDB.DAT file structure
As it was mentioned before, MDB.DAT file contains records about pictures,
assigned to user’s filenames. Files are user’s games (ROMs), with following
extensions: .gen or .bin., uploaded to SD-card.
Schematically, this structure can be represented by following table:
Table 1. MDB.DAT file structure
Game names (filenames)

Game1

Game2
Picture2

GameN

Note 1 to table 1: game names may not match the shown above template. It
is just an example. Learn more in sect. 3.2.1 about naming games in MDB.DAT
file.
Note 2 to table 1: game names (text records) in MBD.DAT file should
correspond with filenames of games, uploaded to SD-card.
Note 3 to table 1:
games may be placed in non-alphabetical
(however, the
feature of sorting is implemented in this program and can be called from menu). If
presence of two same records occurs, the handheld will take picture from the last
of them.
2.1 Using the MDB.DAT file
No matter if you took «standard» MDB.DAT file or made it with the help of
ScreenGopher, it is necessary to do the following:
1. Copy this file to X:\GAME (instead of X the letter of your SD-card is
meant) folder, containing user’s games (ROMs).
2. Rename files (ROM-files with .gen or .bin extensions) corresponding to
records in MDB.DAT file.
For example, if your MDB.DAT file contains 3 records: «Aladdin»,
«SonicTheHedgehog» and «EarthwormJim», the folder X:\GAME have to
be filled, besides MDB.DAT file, with the following files: «Aladdin.gen»,
«SonicTheHedgehog.gen», «EarthwormJim.gen» (or with .bin extension). After
that, while selecting a game in menu you will see a picture for each of this games,
like it was shown on fig. 4.
