Arcana: Arcana - Fastrom

Converts game to use FastROM optimizations:

- Much faster dungeon movement
- Smoother game experience with less lag
- Somewhat faster loading time performance
- 1.1b: (torha/Sarah Shinespark) Minor speedup drawing dungeon tiles.

0.6 to 1.0 changes [torha]
- Minor speed up when creating dungeon tiles
- Upgrade to v0.6
Short explain:
839d59 lda $7f0000,x [7f0040]
839d5d pha
839d5e sep #$30
839d60 plx
839d61 lda $83b251,x [83b350]
839d65 xba
839d66 plx
839d67 lda $83b251,x [83b251]
839d6b xba
839d6c rep #$30
Notice how it uses the stack (pha, plx, plx). A small gain by avoiding the r/w to ram.

tay ; two 8-bit tile data

sep #$30
lda $83b251,x ; tile1
xba
tyx ; tile2
lda $83b251,x
rep #$30
Which fits perfectly.


1.0 to 1.1b changes [Sarah Shinespark]
Removes a useless ADC in $9008 (an event handler) and uses the 3 bytes to add an ORA.
Changes any banks using this method to fastrom banks.
Also, manually changed a lot of JSLs to use fastrom.
