D-Pad issues with PS2 cheat code for Densha de GO! Final

[retroNUC]

Hi, thanks for the website.

Using the cheat code provided for Densha de GO! Final and a Two Handle PS controller (SLPH-00051), the controller is mostly working while in-game, but I'm seeing random flickering coming through on D-Pad inputs that makes menu navigation impossible.

Running a Redump-verified copy of Densha de GO! Final via an up-to-date version of OPL.

Just to confirm:

• The non-Densha controller is connected to port 1.
• The SLPH-00051 controller is connected to port 2.

I assume the OPL version is 1.1.0 (latest stable release). I'd need to know the exact version of the game; you can check it in the SYSTEM.CNF file in the game data (just paste the content in your reply). This way, I can try to recreate the problem.

What does the flickering behave like? Does it happen only for up/down or also for left/right? It'd be great if you could share a video of the issue, to get a better idea.

Thanks!

Hey @marcriera, I know this thread is old but I have the same issue reported by the OP
Game version is 1.02 from the SYSTEM.CNF file:

BOOT2 = cdrom0:\SLPM_655.90;1
VER = 1.02
VMODE = NTSC

I also noticed that in game sometimes both power and brake very quickly "flash", which quickly causes you to lose lives and therefore lose the game. I don't believe it's an hardware issue with the controller because the same thing doesn't happen in Densha de Go 3 or Shinkansen where the controller is officially supported.

I've attached two videos that show the issues.

Thanks in advance!

If it helps, I just tried both Ryojōhen and Professional 2 (Taito Best) with the cheat codes and no issues, those work perfectly.

[marcriera]

Thanks for the report and the videos, it is very odd indeed.

Final is trickier than Pro 2 and Ryojohen because the game's binary doesn't have debug symbols and I have to guess which parts of the code and memory I need to alter. I'll see if I can recreate the issue; last time, when I tested the cheat code, it wasn't working at all for some reason.

Not going to leave you hanging like last time, apologies :)

New code tested and working great on Densha de GO! Final with the Two Handle PS controller (SLPH-00051). Thank you!

[marcriera]

No worries, great to know it's now working. I've just updated the codes for all games to use the new format, just in case.

[vascofg]

@marcriera I'm sorry to report that I still experience the same issue with the new code in Final.
Both the issue in the main menu and the issue of throttle flashing while in game

I have tried to recreate the issue but no luck. I've tested three different controllers and played for a while and also left the controllers idle at the menu, but everything seems to work. It may be more complicated and depend on other specific conditions. Just to confirm:

1. Which PS2 model are you running this on? (the model number on the sticker on the back of the console is fine, mine is a SCPH-50004, for example).
2. How are you running the game and applying the cheat codes? Actual CD with ps2rd, OPL, etc.
