Luciano Ciccariello 0df33d1975 Texture render support (#934) ... Technically unimpressive, but I had to go through quite a good amount of changes. Here is the full changelog to make everything work: * Ensure `ResetPlatform` is always called to avoid memory leaks * Add `g_RawVram` to emulate the PS1 VRAM * ~~The engine will load the optional file `disks/vram.bin`, a RAM dump from an emulator~~ * SDL2 will create 256x256 textures on-the-fly whenever a specific tpage is requested via `GetVramTexture` * The function `GetVramTexture` caches the last called tpage to avoid tanking the performance * `GetVramTexture` for only renders 4bpp and 8bpp textures with their specified palette * Remove `SDL2_image` as the font is now loaded straight from the VRAM * Calling `VSync` will call the set callback, which the game uses for DMA operations * `MyLoadImage` is not yet implemented, but it is a placeholder to then interact with `g_RawVram` * The menu font now uses the texture found in the VRAM * Plugged a custom version of `LoadFileSim` * The file `sim_pc.c` is similar to the original game's code but it is used here to load files from custom paths * Using F5, F6 or F7 can dump the VRAM content on-screen, respectively in 16bpp, 8bpp and 4bpp There are new graphical glitches on the font. In some occasions it appears black. It seems to be related to a flag in `P_TAG.code`. I plan to dig into it when I can render entities on screen to avoid potential mistakes. The same problem is present for the first half of Alucard's portrait. It seems to be related when a texture is transparent? 🤷 I am not sure why the font is completely corrupted when entering in the Equip menu. It is hard to understand if I introduced any regression. Maybe the glitch was always there but it was hidden since I was always forcing the font texture to be rendered. EDIT: Implemented `LoadImage`, `SaveImage` and `ClearImage`		2024-01-01 23:31:56 +00:00
