@Hex Here is the text in /boot/config.txt

# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=128 128 60 1 0 0 0

display_rotate=2

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256
overscan_scale=1

Hex

append width=128 height=160 and reboot and let me know if that works.

Edit: Also change this line hdmi_cvt=128 128 60 1 0 0 0 to hdmi_cvt=128 160 60 1 0 0 0 in /boot/config.txt

width=128 height=160

On /etc/modprobe.d/fbtft.conf

Hex

yes

retroprogrammer

@Hex Like this:

options fbtft_device name=fb_ili9163 gpios=reset:25,dc:24,led:23 speed=40000000 bgr=1 rotate=1 custom=1 fps=60,width=128 height=160

Yes or No?

retroprogrammer

@Hex Now the screen is all being used, thanks :) but the colours are still wrong and everything is still small know how to fix that to?

Hex

can you post a photo of what you mean by colors are wrong ?

retroprogrammer

okay

retroprogrammer

just check this link:https://imgur.com/gallery/Yv7Hx/comment/1225358395

The logo that you see is of the GameBoy Advance, it is suppose to be blue, yeah?

Hex

How about you start a game and check ?

The icon is based on your theme. change the theme to change icons. I dont know what you are supposed to see.

retroprogrammer

Even when I play a game all the colours are mixed up, I am using the carbon theme and the Gameboy advance logo is blue, but on the screen it is red

Hex

Use this as your fbtft.conf

options fbtft_device name=sainsmart18fb gpios=reset:25,dc:24,led:23 speed=40000000 bgr=1 rotate=1 custom=1 fps=60 width=128 height=160

and reboot

retroprogrammer

@Hex Now I have a white screen

Do I have to change wiring?

Hex

just revert it then. change name to fb_ili9163

I ont know what is causing the color problem. can you post a new picture of how a game like Zelda on Gameboy color looks like ?

retroprogrammer

@Hex Here is the pictures of Zelda on GBC:https://imgur.com/a/6JHBZ

Hex

@retroprogrammer i see in your fbtft.config file you have bgr=1, can you remove it and let me know if that works?

That should resolve your colour problem

retroprogrammer

@Hex No still same problem

retroprogrammer

@Hex Is their a way of making the screen a bit bigger?

Hex

how about bgr=0

The problem is that your blue and red channels are switched and this is the only way to resolve this. If this doesnt work then you will have to try different device names as some device_names dont support the BGR parameter (let me know if you need those).

From the author of fbtft:

bgr :
Set BGR bit (supported by some drivers). Use if Red and Blue is swapped. Default is don't touch.

The best way is to buy a new screen that is bigger. Else you could try my Viper frontend, which is in works currently. Even i was unhappy with the performance of ES on smaller screens. Here are some of the photos of my frontend. The screen is 320x240 @ 2.2inch.

@Hex bgr=0 doesn't work either, I think the red and blue are swapped around or something, I need to know the device_ names please.
