Thank you for posting this, i made it sticky.
Also be aware:
you need to alt tab out and press option keys.
the game hijacks keypresses in fullscreen mode so it might not work when pressing hotkeys.
The hotkeys work fine, as long as you open the trainer AFTER you've loaded into your game. I start RDR2, load my game, and as soon as Arthur is controllable I ALT+TAB out and start the trainer, then ALT+TAB back into the game and the hotkeys work as designed.
If you start the trainer before starting the game, or start the trainer while at the main menu, the game inhibits the use of the hotkeys.
Hope this helps those who are having issues using the NumPad buttons.
Kudos to CasualCheater who actually take the initiative and effort to open a new message board to address this money issue that have plagued so many players. Well done Sir !
Unfortunately, despite following all the suggestions here and from the main forum, the money still reset after I make a purchase. Yes, I did turned off Item Give Max before going to the vendor. Yes, I did turned off Money On Pickup before buying any stuff. Even set money to just only 1000 and still money reset.
Will keep trying other options and settings hopefully can find a solution soon.
You set the money to a $10.00 value and it reset? What may I ask did it reset to? I noted the first time I successfully used the trainer I thought I set it to $5,000 because I entered 5000 into the box. Went in game and picked up some cash and it advanced it to only $50.00. Afterwards I added a few more zeros as I noted it counts the last two digits of the value in the box as the cents. So if you wanted $1,000 total you should set the value in the box to 100000. Then pick up cash to advance it, turn off the stated options and then try to buy something. It's worked pretty flawlessly for me, and as long as I don't forget to disable those two options the money has stayed with me since I gained it.
