So I've been working on the Map Screens, and I think I've finally gotten this figured out.
- The tile data for the sprites are stored in the AMAP#.ADD files.
- Location tiles are 32 pixels tall
- Title tiles are 24 pixels tall
- Horizontal sizes vary, but for the first map it's 160 for the locations, and 152 for the title.
- The screen runs in the 352x448 resolution mode.
The resolution causes some issues with the text when it's drawn. The VDP1 sprites for the text are actually scaled down to half their horizontal size when drawn to the screen. So they're actually 80x32 and 76x24 respectively. This is why things were looking so poor.
So with this in mind I think I've gotten something that looks passable. Just using a larger font for the location data seems to have mitigating the scaling issues for the most part, however for the map title I had to draw the text at 76x24, and then column double it to 152x24 when saving it in the data file. Anything else I tried looked horrid. So while this works, it sadly means I only have half the horizontal resolution to work with in reality for the title of the map.
