After encountering issues with the current data.grf, I decided to start from scratch and overhaul the entire process. The result? A significantly reduced file size for the data.grf
Previously, the data.grf weighed in at around 2.45GB, but now it’s down to just 2.15GB.
In addition to the file size reduction, I’ve added 275~ mini maps to maps that were lacking them.
The entire folder, including BGM, now stands at 2.96GB.
What was done to the poor data.grf?
Besides cleaning up unused sprites from npc and mob folders, now I converted all .BMP files to be 8bit, this doesn't affect quality on a game like RO, instead, it actually makes it easier for the client to handle those assets.
.JPG and .PNG were treated as well but with some differences.
Feel free to report any issue here
