GeoffR, thanks for the patch.
I adapted the font size to auraHD:
Code:
<Patch>
patch_name = `Custom fonts sizes`
patch_enable = `yes`
# Values for replace
replace_int = CB4AD8, 12, 10
replace_int = CB4ADC, 14, 12
replace_int = CB4AE0, 16, 14
replace_int = CB4AE4, 17, 16
replace_int = CB4AE8, 18, 18
replace_int = CB4AEC, 19, 20
replace_int = CB4AF0, 20, 21
replace_int = CB4AF4, 21, 22
replace_int = CB4AF8, 22, 23
replace_int = CB4AFC, 24, 24
replace_int = CB4B00, 25, 25
replace_int = CB4B04, 26, 26
replace_int = CB4B08, 28, 27
replace_int = CB4B0C, 32, 28
replace_int = CB4B10, 36, 29
replace_int = CB4B14, 40, 30
replace_int = CB4B18, 44, 32
replace_int = CB4B1C, 46, 34
replace_int = CB4B20, 48, 36
replace_int = CB4B24, 50, 40
replace_int = CB4B28, 52, 44
replace_int = CB4B2C, 54, 52
replace_int = CB4B30, 56, 56
replace_int = CB4B34, 58, 60
