Hi, I tried to patch the game Parasite Eve 2 Pal Fr (CD1), I followed your instructions, but the game doesn't start at all. I tried to start it with PS Pal, with action replay, and also with importplayer, nothing work, What I did wrong ?

Hi,

1)Does an unpatched copy boot? 2) What CD-R and burner? It sounds like bad burn/cd-r media since the protection doesn't trigger till mid-game IIRC.

2nd favorite game after the original BTW

1) No, unpatched copy does not boot too. 2) I'm using Verbatim CD-R (https://www.amazon.co.uk/dp/B0009PGVL8/?coliid=I2J8M6UICOJ9S6&colid=2UWREROGYQFHB&psc=1&ref_=list_c_wl_lv_ov_lig_dp_it_im), and imgBurn, in x2 speed.

The patch seems to work, I tested on emulator (both unpatched and patched), at a certain point the game does load (right when Dryfield start) with unpatched, but works well with patched.

Actualy, the thing I tried to determine is if the game can be forced to NTSC 60hz with ImportPlayer, I have to know before buying the game, maybe you know this ?

Sadly you bought one of the worst CD-Rs. That is what is preventing it from booting, the PSX can not read the data from poor quality CD-Rs. The protection nor the patcher are not at fault for this for sure.

I have a web page documenting how the CD-R can cause this here https://alex-free.github.io/psx-cdr/

You want to buy CMC Pro (best) or Verbatim DataLifePlus (still ok).

I am unsure about the 60hz.

I read your guide, nice works !!!. So, I'm looking for better CD-R quality, here are some of what I found :

01

10 CD-R Taiyo Yuden JVC CMC PRO 52x 80 min

02

Verbatim 10 Slim 48x CD-R DataLifePlus 80 min

03

4 X TDK CD-RXG 74 AUDIO Digital 74 min

04

VERBATIM DATALIFE PACK 20 x CD-R - 650MB/74 min

05

9 CD-R Verbatim DataLifePlus 650MB/74 min

Can you help me to choose what is the best choice please ?

Any advices please ?

Sry for the late reply.

I think the CMC Pro is best. The DataLifePlus 74min/650mb is 2nd. Either is perfectly ok for the PSX. Both have pros and cons going for them, but they are much more compatible with the PSX in comparison to what you've been using.

I'm to you one more time, Just to be sure, about these CDs https://www.ebay.com/itm/334107508647 can you confirm me that is possible to burn it without any issues with my laptop burner ?

Before you buy any CDs read Do modern burners/CD's make lower quality PS1 backups?

I know laptop burner is the worst, but this the only one I have, so do my laptop burner is compatible with these CDs ?

There's no way to know with a laptop burner. It is extremly more likely to work with those CD-Rs but most laptop burners are not up to the task.

If you can find non-JVC CMC Pro I'd go with those.
