You need to clean the names with this command on batch (linux command line) :
rename ‘s/\(.*\)|\[.*\]| //g’ *
(Or use Advanced renamer for windows)
3) You need to resize the width to 135 px.
To resize in batch you can use imbatch on windows. You will resize the width but be sure to keep the ratio for the height.
Finally before resizing you need to choose the good filter. Some of those are foggy AF so choose the one named ‘Nearest’, you can see the final result on the left bottom corner.
If you end up doing some, please share them with the community in r/bittboy subreddit!
My Bittboy theme
Pimped DeckUI
Since some people asked me wich theme I use on reddit, i will share it here but I want to stress out that i didin’t made it. It’s a patchwork of a few themes stitched together. It is mainly based on DekUI v1.0 by Jutleys.
Here are the instructions to install it
################ # Pimped_DekUI # ################ This Gmenu2x theme is based on DekUI v1.0 by Jutleys. I Pimped this theme with custom emulators and apps icons i scraped from other themes. This is not an original work by me and all the credit are due to various authors. I made this because I loved the look of it. ############################### # How to install this theme : # ############################### 1) Copy the "Pimped_DekUI" folder to the /gmenu2x/skins/ directory in the main partition of the SD Card. 2) Choose the theme inside the bittboy settings > skin submenu 3) There is a few wallpaper, choose the one you want inside the settings. I love one named dekthro-two-plus.png ####################### # Skin menu options : # ####################### I will give you all my parameter inside the skin menu so you can have a good scale for the text and all. Skin : Pimped_DekUI Wallpaper : dekthro-two-plus.png Background scale : Original Skin backdrops : Menu Only Font face : Default Font size : 11 Title font size : 13 Section bar layout : Classic Section bar size : 40 Bottom bar height : 16 Menu columns : 4 Menu rows : 3 Link label : ON Section label : ON
