Index DB issue on saving the game

[muditjuneja]

Hi Team, I am getting below error -

NotFoundError: Failed to execute 'transaction' on 'IDBDatabase': One of the specified object stores was not found.
    at lcache.ts:113:41
    at new Promise (<anonymous>)
    at si.put (lcache.ts:107:16)
    at bundle-storage.ts:88:10
    at async Bi (player-api-load.ts:79:11)
    at async main.tsx:55:29

This happens when the player is loading hinders game saving. I can say that I am seeing it in a flaky manner where sometimes it happens and sometimes it doesn't and saving flow works.

Can you help here?

Looks like browser bug, what browser do you used?

[muditjuneja]

I am on Brave Browser which is based out of chromium engine only.

Can you provide more details, like what game you playing, where, etc.

[Benman2785]

this is the "second" save i did this game

Is it reproducible? Can you share bundle to test?

[Benman2785]

yes it is reproduceable

1. go to: https://hoffmeister.li/js-dos/
2. choose either "Perry Rhodan: Operation Eastside" or "BotF *"
3. play game and save at one point
4. quit game and shut down windows in js-dos
5. choose "save progress" = yes
6. 1-5 again = bug reproduced

here the package i use: https://hoffmeister.li/js-dos/games/PROE.jsdos (530mb)

ps: first save always works -> but 2nd,3rd,nth save doesnt work

mh, chatgpt says the problem is that i use multiple img files in my bundle -> one for Win95 and one for the game (yet i prefer this method)
will try to make one with game and OS on same img file -> maybe i have time for that tomorrow or within next week

You are trying to use the save/load feature with .img files, which is not intended to work. This is because every change made to the image filesystem requires storing the entire changed image, so it will not work. Instead, you should use qcow2 images. Once your bundle is ready, you need to apply sockdrive on top of it, as explained here: https://js-dos.com/publish-sockdrive-bundle.html

This is the only way to make larger images work with saves. Also, I wonder why you created your own Win95.img. I highly recommend using one of the pre-created bundles from js-dos. Please read this documentation: https://js-dos.com/jsdos-bundle.html

mh, currently i have problems getting sockdrive to work -> i guess i need CPU v-Flag -> but my hoster doesnt allow that for my KVM

YET it kind of works now -> i used a 966mb HDD, installed Windows 95 + DX5.2 + Game -> could save several times (round 1, 10 and 50) without problem // 2GB is to big for that -> as we are limited by array-length

Sockdrive is pure static solution, you only need a linux pc to convert js bundles to sockdrive bundle and then you can serve it as static website

ok - i try to install it when i have more time -> last 2 tries didnt work :/
