I'm running Classic Workbench 3.1 with WHDLoad uisng E-UAE, and by launching the defaul app "E-AUE" that cmes with Chrysalls Pack.

Everything is working fine, except that the emulation screen is too smal, and I want to play in a screen at least double in size or full screen. This is part of the configuration file:
cpu_type=68040
gfx_width=640
gfx_height=480
gfx_linemode=double
gfx_center_horizontal=smart
gfx_center_vertical=smart
gfx_fullscreen_amiga=no
# picasso is only supported in SDL build
gfx_fullscreen_picasso=yes
z3mem_size=32
gfxcard_size=4
cpu_speed=max
floppy_speed=0
sound_output=normal
sound_bits=16
sound_channels=stereo
sound_frequency=44100
chipset=aga
show_leds=true
kbd_lang=en
scsi=true
scsi_device=ATAPI

# joy<n> where n is lowlevel unit in amigaos target. In SDL target it's be the enumeration order.
joyport0=mouse
joyport1=joy1


# overlay display
amiga.use_overlay=yes

# screen type (accepted values are:public, custom or ask)
amiga.screen_type=public

I'd very much appreciate if someone could share the settings that I need to change to be able to play in a bigger emulation window or full screen.

Thank you.
