I will look for it later, in 1.18.1-661- the game can still be opened without freezing.
i still don't know where the issue started v1.18.1-680- started freezing i checked again

[IrfanH495]

If it started to freeze from v1.18.1-678 that would mean the recent Infrastructure commits, may be the #19818
Is that game have multiplayer feature?

[IrfanH495]

there is no information on gamefaqs

I think there is but I've never tried it

[IrfanH495]

eh, it turns out it doesn't freeze if I enable networking/wlan
Enable built-in pro ad hoc server and reload the game.
try it again in version 1.18.1-678-

Yes i've checked the game too just now, it's because the game failed to initialize Networking/Adhocctl if WLAN is disabled, it doesn't need the built-in adhoc server, just need to enable WLAN.

I think it's the correct behavior not to be able to initialize adhocctl when WLAN is disabled (but someone need to confirm this on real PSP tho), because some games (ie. GTA VCS) can only leave multiplayer menu by disabling WLAN during adhocctl failure (ie. lost connection to the adhoc server without able to reconnect again), due to infinite attempt of retries the game did and got frozen, and the game only checked whether WLAN is on/off as a way out of multiplayer mode.

PS: The recent changes related to this is at sceNetAdhoc.cpp:

int sceNetAdhocctlInit(int stackSize, int prio, u32 productAddr) {
	INFO_LOG(Log::sceNet, "sceNetAdhocctlInit(%i, %i, %08x) at %08x", stackSize, prio, productAddr, currentMIPS->pc);

	if (!g_Config.bEnableWlan) {
		return -1;
	}

Hmm.. JPCSP doesn't seems to checked WLAN during sceNetAdhocctlInit, may be we should allowed it too, like before.
@sum2012 do you have this game? if you have it, could you test it on your PSP to see whether the game can boot with WLAN off.

[hrydgard]

Yeah this might just be a case of moving that check to some other call. Will look into it after dealing with the socket remapping.

@anr2me
Real PSP work what even the game can boot with WLAN off or on.

Thanks for testing :) i guess we should remove that WLAN check.

[anr2me]

Hmm.. it's strange that i can't sync all of my ppsspp forks using the "Sync fork" -> "Update branch" at github.com, it doesn't seems to respond at all.

[anr2me]

Something does feels strange, since i can't delete this duplicated post too :(
