Hey, NewB question about chr rom.

I do have a .rom file containing my sprite and background tiles, data. It was 8kb.

Today I switched to a 16kb .rom file (created using yy-chr.net ).

So far so good. So i changed my cfg a bit and put $4000 for size instead of $2000:

ROM2: file = %O, start = $0000, size = $4000, fill = yes;

im using cc65 compiler btw

Seee attached rom, with mesen, or w/e , in TILE VIEWER , I know its in there, you can see my new sprites tiles !

My question. How do I actually access it ! DO I need a specialised mapper ?

Common NameAddressBitsTypeNotes
PPUCTRL$2000VPHB SINNWNMI enable (V), PPU master/slave (P), sprite height (H), background tile select (B), sprite tile select (S), increment mode (I), nametable select / X and Y scroll bit 8 (NN)

do I need to use $2000 bit 3? i dont think so, it just change the sprite tiles to $0000 to $1000, vice versa. So How Can I actually use the tiles at $2000 and $3000 !

Im not sure sure what to tire, tired of reading lol. help !
