== Running Debug Builds ==
Unlike release builds, development builds
are nominally configured for serial port debugging. If there is no serial cable attached, or a terminal program is not running on this port, ScummVM _will_ hang at the " SEGA" logo screen or a black screen due to RS232 flow control (the Dreamcast fails to get Clear-To-Send).
If you don't have a serial debugging cable, then you can use the development builds from [http://buildbot.scummvm.org/builds.html here] which are not marked "with Serial Debug"
, or if you are compiling yourself, then this can be disabled by editing the relevant configure script line to ensure that the enviroment variable DEFINES contains the parameter "-DNOSERIAL", which is otherwise only ensured for release builds.
Also, the development build plugins are usually larger than the release ones i.e. unstripped/debugging symbols. Thus as previously noted, if the combined size of the engine plugins on the CD is larger than the available memory, this will manifest as either a lock up of ScummVM or as a system reset before the selection menu appears.
