Hello guys this is just a test code
I made this code for true 240p display, not just deinterlace. Code is in PS2rd format

901133D0 0C044C9C //enable code
20101CD4 24110000 //sets non interlaced mode
001555B4 00000002 //12000020 to 02
//L3+L2
D01F40CC 0C00FEFD //joker
201EB860 000510A0 //vram region
201EB864 00008000
201EB888 000510A0
201EB88C 00008000
201EB8B0 000510A0
201EB8B4 00008000
201EB868 0381A27C //resolution

//L3+R2

201EB888 00011428
201EB88C 00000000
201EB8B0 00011450
201EB8B4 00000000
201EB868 0183227C
201EB86C 001BF9FF

press L3+L2 to activate , L3+R2 to revert to default, so you can nicely see the difference. The default image and main menu etc will be shifted lower, because I centered the original untouched image. The ingame menu which appears if you press Select will display only in default mode because it is rendered only to the altered buffer.

I made the code mainly for Gun Frontier and Rastan 2, maybe the others will work didn't test them all(not sure if all of them renders the original picture to the same vram region). Note that Gun Frontier will be in TATE mode because that is the original format.
Before you get excited there are problems, and will try to explain.
So this game and almost all the other 2d games on PS2 (the ones I tested), render their original resolution image somewhere in the vram, then it uses this image to upscale, apply filters etc.
So what the code does, is sets the PS2 to 240p(320x224) and displays the region of vram where the game renders the original 320x240 game. But because this is not the main buffer to display(my guess) things will not be drawn in a synchronous mode, so you wil have some errors on screen(like a constant tear line with glitches).

I made similar codes for the capcom collection disc, sfzero collection, offcourse those cps games are 384x224, so I displayed them in 384x224, which the PS2 supports contrary to popular beliefs. Off course all of them exhibits the same problem mentioned above.

Anyway it is still nice to see them on CRT at their native resolution without any stretching, filters etc and many of them are playable even with the problems mentioned.

The same is valid for 3D games, for a lot of them you can find in the vram cleaner buffers, without effects apllied to them (examples Tekken Tag US version, Ico, GT3,4, Enthusia and many more)

My knowledge and skills got me this far, maybe someone more skilled can somehow modify the game rendering to use this unaltered buffer in a correct way without glitches.

Hi!

I just stumbled across this, and I’m amazed!

I’ve been testing these codes, and it’s incredible what you’ve accomplished here. I didn’t even know something like this was possible. You did an awesome job!

The ability to toggle it using button combinations is genius—thank you for sharing!

I also tested other games in the compilation. Some of them appear slightly shifted, but they still work.

Do you think this could be applied to the other Taito Memories titles? (Jokan, Gekan II, etc.)

I made similar codes for the capcom collection disc, sfzero collection, offcourse those cps games are 384x224, so I displayed them in 384x224, which the PS2 supports contrary to popular beliefs. Off course all of them exhibits the same problem mentioned above.

This almost sounds too good to be true! Could you share these codes? Having those games run at their original CPS2/3 resolutions would be amazing.

I’m surprised no one replied to your post! It’s been a while since you originally posted this, so I hope it’s not too late to reach you! Thanks.

Didn't see this at its moment either, otherwise I'd have thanked asasega as well. Maybe the process to get this working is a bit too convoluted, hence the lack of replies? At least it seems so for me, having never used a cheat code before. But just that this exists is neat anyway. I wonder if the graphics filter is noticeable at 240p in this case.
