VN3DS

VNDS is a syntax created for the purpose of playing visual novel games on multiple devices. Dozens of popular visual novels such as Fate Stay Night, Ever 17, Saya no Uta have been converted to be VNDS compatible and thus, when this is completed, will be 3DS compatible.

What's done:

Text, cleartext, label/goto, delay, jump, setvar, gsetvar, save/load, "CPU bgload" "CPU setimg", choice selection, IF/FI, random

what's not done
Music/sound (ogg loading in LPP is a W.I.P. Crashes quite often right now and been disabled)
Fadetime
Start/End colored text

This is what if/fi conditionals look like in a very conditional heavy scene of Ever 17. Can't even imagine how someone managed to do this in VNDS. Looks like nonsense.

Quoted from IF/FI:

Future plans.

Automatic unzipping of .novel and .zip assets.

Clean up all the awful programming.

GPU rendering to allow imagescaling. VNDS has been widely adopted on Android and other devices with higher res screens than the DS's 256x192. What this means is that newer VNDS ports in some cases aren't actually compatible with DS. This would fix that.

This is actually a feature of later LPP commites, only problem is that LPP has problems with GPU rendering JPGs currently. Thinking of on the fly converting the JPGs via CPU into BMP and then GPU rendering and storing the newly converted BMP version. Wonder if that would work... Or just wait for LPP to support GPU JPGS.
Attached ZIP of latest build of LPP 3ds/3dsx/elf, and the index.lua script which goes on the root of the SD. Obviously I can't distribute the VNs with it so you'd need one of those and it's hardcoded to open /vnds/Saya/script.s02.txt so you'd need to change that. Because there's no GPU scaling you'd need to batch resize all the assets down to 3DS size (mine are at 320x24)
IDK. Maybe someone smart could help me with the IF/FI thing. This really isn't meant to be playable. Without if/fi support it actually can't get past the main menu. It can display pretty much the whole game, just not make it through the main menu and conditionally move through the script.
