Need help disabling the HUD on a very old PS1 ROM
« on: June 04, 2020, 01:45:24 pm »
This isn't exactly a hack but I need to disabled the HUD on an old PS1 ROM.  It's the Rockman Dash Beta Trial (Capcom Friendly Club disc).  I've tried with cheat engine in ePSXe and retroarch's value search but can't find it.  Should be 2 bit but nothing I found has worked.
 
How would I go about doing this, or would someone be willing to help?  Been searching forever now.

Find how to disable hud by searching for cheats? I don't think this will work. Also, 2 bit, what? 2nd bit? 2 bits? 2 bytes?

If you can recreate 2 similar ingame situations with and withoud hud, with as less other differences as possible, you can try to switch between these 2 saves and check for what is different between them

I managed to luck out and found these very quickly:
Code: [Select]
; check byte to display HUD
$8009A910 = player health
$8009A930 = player weapon
$8009A950 = boss health
The game uses bit 2 to display each of the HUD elements, so a value of $01 will just hide them visually.

This is repeated from the hack ideas thread.

Thank you, works great :] I was looking for the value in the wrong way before.

I read somewhat regularly on this forum and I didn't know that. This forum isn't exactly teeming with activity and I appreciate this activity in this thread.

I'd rather have this thread too and have something more to read  :beer:
