IS Viewer emulation is currently gated by a command-line flag. All
other major emulators supporting ISViewer (Ares, dillonb, m64p) enable
it by default, and it does not seem to create any problem.
To help homebrew developers discover the feature without showing logs
by default, change the code to always emulate the ISViewer hardware
and add a warning if the ROM uses it but the command line flag was
not specified. This should point users towards correct usage, and
prevents possibly-verbose logs to be shown by default.
Nintendo 64 homebrew community is standardizing on a convention to
declare the save memory type as a header flag. This convention has been
first introduced by EverDrive 64 as a way to handle games not present
in their DB, but it's been since adopted by libdragon as well.
With this commit, cen64 will automatically configure the correct savetype
for homebrew ROMs using the special header flag.
I've also added support for a 1Mbit SRAM savetype. This was never used
in commercial games but it is available with EverDrive64 and is one of
the possible configuration options. It costs nothing to support it and
may help development of homebrew games that decide to use that savetype.
Currently, the experience of cen64 binaries of Windows is not the
greatest, to be kind. If you get the binary and double-click on it,
you get nothing (no feedback whatsoever). If you run it from the
console, you get nothing (no command line help is shown). I am not sure
how Windows users ever manage to use it.
This happens because the binary is linked as a windowed application,
but when run with no command line applications, it exits after printing
the help with printf, which does nothing since no console is
attached to the windowed application.
This PR improves the usability on Windows. It compiles cen64 has a
console application (as was meant to be used), so that the help text
or any other stdout/stderr output is now visible on console. Moreover,
to provide a decent experience to users double-clicking on the
binary, it displays an error message explaining that it should be run
from the command line instead.
Fixes a Segfault when loading Dezaemon 3D.
* Unfortunately, Dezaemon 3D does not actually work yet. It appears to
fail the SRAM test, which still needs further investigation.
Adds an option alias for sram256k to disambiguate with new sram768k option.
When -is-viewer is passed on the command line, create an IS Viewer
object that intercepts writes at 0x13FF0000. This is used by Ocarina of
Time Master Quest Debug to log debug messages.
The messages are encoded in EUC-JP, so we bring in iconv to convert that
to UTF-8 so the messages can be printed to modern consoles.
Props to jrra (@jkbenaim) and spinout for reverse engineering the
interface and documenting it: http://wiki.spinout182.com/w/IS64
Add a "running" boolean to the master device struct, and set it to false
when the main window is closed. All the tight inner while (1) loops now
become while (running).
Closes#24
This field is required in order to distinguish between regional
versions where the game ID is the same but the save type differ,
such as the Castlevania games.
Also added more Japanese-specific game IDs and edited some descriptions.
simer suggested (and implemented) the use of ROM IDs instead
of titles: "I've also found that the header name in some cases
are too inprecise, for example "TOP GEAR RALLY" has EEPROM 4K
for the Japanese and European versions, but not for the American.
