= Requirements = | |||
Here is what you need to run ScummVM on your Nintendo 64: | |||
*Nintendo64 (haha...) | |||
*N64 Gamepad | |||
*N64 Mouse (optional, gives better game experience) | |||
*Controller PAK / FlashRAM cart (for saves) | |||
*Flash Cart or copier (like Myth N64 or DoctorV64) | |||
*N64 Memory expansion (this is _almost_ a requirement) | |||
= Build cart images from binaries = | |||
ScummVM N64 cart images are composed by two parts: a binary with executable code | |||
and a romfs image, containing game datafiles and other useful data. | |||
Prebuilt binaries needs to be joined with a romfs image containing datafiles | |||
from _YOUR_ games. | |||
To generate a romfs image under linux/unix you need 'genromfs' tool from | |||
http://romfs.sourceforge.net/, create a directory, copy game data inside, | |||
and then generate the romfs image. | |||
<pre> | |||
mkdir GAMEDATA | |||
cp -a ../games/mygamedata ./GAMEDATA | |||
genromfs -f ./ROMFS.img -d ./GAMEDATA -V romname | |||
</pre> | |||
This creates a ROMFS image with 'mygamedata' directory inside. | |||
Now you need to join this with the appropriate scummvm engine binary: | |||
<pre> | |||
cat scummvm-bass.bin ROMFS.img > scummvm-bass.n64 | |||
</pre> | |||
Now the last step, you need to fix the checksum of the image, there are various | |||
tools for this, i normally use ucon64. | |||
<pre> | |||
ucon64 --n64 --chk scummvm-bass.n64 | |||
</pre> | |||
This gives you a n64 cart image you can use with your flashcart/copier to play | |||
the game. | |||
<b>NOTE</b> | |||
Some copiers requires additional treatment of the cart image before uploading: | |||
the DoctorV64 for example requires the image to be byte-swapped and padded to | |||
the nearest 2mb multiple size. You can use ucon64 tool to perform these changes. | |||
<pre> | |||
ucon64 --n64 --v64 --padn=16777216 scummvm-bass.n64 | |||
</pre> | |||
You are then ready to upload the image to the cart and play! | |||
