Click Load and select your Homebrew's EBOOT.PBP file. You'll also need to download the Homebrew you plan on converting. You should be able to find them pretty easily with a quick google search. You will need to download a few programs first. Recently I found out how to convert them so they can be hashed and worked on, and figure I would share. In regards to screen size I find if you select 'custom' then holding 'L' until the screen goes as small as possible before resizing with 'R', this will give you the largest most correct aspect.PPSSPP can run homebrew natively, but the issue is that we cannot hash it as it is not a. Once the game is loaded you are able to toggle various options by pressed the home button, such as screen size, disc speed, key config. go to game on your Memory stick and your PSX game should be there with the ICON you selected (and any other added pics/movies)

Keep the EBOOT in the named folder and drag the folder into PSP/GAME of your memory stick. Now open the output folder (the one you selected for the game to be saved in after converting), You should see a folder named after the game you've just converted containing a 'EBOOT.PBP' file. usually around 30% but I've had games that have compressed in excess of 80%! it also compresses the original PSX file. for the icon image the file must be ICON0.PNG I usually only use the first one 'ICON IMAGE' as this is all you need to easily identify your game from the PSP's XMB. the right hand set of dropdowns allows you to select various images and videos to accompany your game icon.

*NOTE: this would be a good time to select OPTIONS and then FOLDER then under 'auto-create folder on convert' select create game title folder (this makes it easier to locate your PSX games if you convert quite a few, if you don't tick this it will save the eboot.pbp in a folder named after the PSX games serial number. *NOTE: long file names and/or foreign characters may corrupt the data, shorten the Game Title and Main Game title if needed. simply select the folder you would like the completed file to end up in.

Once selected all of the left hand side should be auto-filled for you except the output folder. Select the 'ISO/PBP file ' dropdown and find the ISO, IMG or BIN of the PSX game you wish to convert. Then choose the interface you wish to use (I always use Classic because I find it's a lot easier and gives the same results)
