How to install and play Curse of Monkey Island on Android

Image
There are some great adventure games on Android already. I can warmly recommend Thimbleweed Park or The Silent Age for example. But what if you wanted to play an old classic that cannot be found on Google Play? ScummVM is an app that can emulate these games, if you have the data files. And Curse of Monkey Island is one of these classics. Installation Purchase Curse of Monkey Island from gog.com or Steam (costs about 5€) Download and install it with the GOG Galaxy launcher ... Or Steam Locate the Curse of Monkey Island install directory on your PC Copy the directory to your Android phone, either with a USB cable or on the SD card with an adapter Install the ScummVM app on your phone Start ScummVM and press "Add game" Find the game folder on your phone, select it and click OK.  If you have trouble finding the folder, I made a separate guide for that. Now you can start enjoying Curse of Monkey Island! These instructions should also work on an iPhone. Controls The game is or

How to get rid of coil whine just by tweaking BIOS

Finally. No more ringing in my ears! I had a really bad case of coil whine with my computer. In the end I fixed it just by tweaking the BIOS! The coil whine was at it's worst when the PC was idling or under a light load.  Coil whine is a high-pitched sound that is produced by coils resonating at a high frequency. It is really hard to sense where exactly it's coming from. This is because humans cannot sense direction for high-pitched sounds. At first I thought it was my graphics adapter. So I bought a new used one. But the ringing was still there after the upgrade. Next up, I suspected my PSU was the culprit. So I changed the power supply to a newer 80 Plus Platinum model. I hate changing the PSU. And it didn't help. So it looked like my motherboard was the cause. It's an older ASUS motherboard, P8H67-V.  After googling around a bit, I found people talking about ASUS motherboards and coil whine when power-saving features are on in the BIOS . The so-called "C-state&

How to fix the weird audio bug in Kingdom Come: Deliverance

Image
  Kingdom Come: Deliverance has a bug which makes the sound come out muffled or like the characters were talking far away or through a tunnel. This seems to be because the game thinks you are using multichannel surround sound. There seems to be no option to change the audio mode in-game. Instead, you should change your audio settings in Windows by following these directions: Press the windows key Type "Choose your output device" and select the search result. Select "Device properties" under the Output caption. Select "Additional device properties" This dialog will differ depending on your audio hardware. Go to the Advanced tab. There should be a selection for the default audio format. You should select something like this: 2 channel 44100 Hz audio. I had my Focusrite audio interface set up with 8 channels 24bit 44100 Hz, and that caused Kingdom Come to think I have surround sound. After changing the channel amount to 2 the audio started working correctly.

How to fix the Anno 1404 out of memory error

While playing Anno 1404 Venice multiplayer in local LAN , I had some crashes on one of the PCs. The game suddenly shows a message saying "You no longer have enough memory" and then crashes after a while. I found several tips on the internet on how to solve this. But for me, this is what worked: 1) Download this tool called 4GB Patch and run it on these four .exe files: \Anno 1404 Gold Edition\Addon.exe \Anno 1404 Gold Edition\Anno4.exe \Anno 1404 Gold Edition\tools\AddonWeb.exe \Anno 1404 Gold Edition\tools\Anno4Web.exe 2) Reduce graphics quality to medium or low. This allowed us to play long sessions and I never saw the error again. I don't mind the graphics being a bit crappy if works better. If you're looking for help on how to play Anno 1404 in the local network, check this guide !

Fix for Focusrite Scarlett blue screens on Windows 10

UPDATE: Focusrite have released a new version of their driver , which is compatible with all the 1st-generation Scarlett devices. So there is no need to install old drivers anymore! Recently I got a used Focusrite Scarlett 2i4 (1st gen) and I was very pleased with the sound and feel of it from the start. First thing to do was to download the driver from Focusrite's official page . Their drivers still work for Windows 10, although not officially supported. Then I plugged it in, and... It didn't work. I had plugged it to a blue USB 3.0 port. After trying one of the black USB 2.0 ports, it worked fine. And it sounds very nice! Unfortunately, not long after I got it my Windows 10 PC started bluescreening once a week. After a bit of wondering I realized the issue: The USB cable I used must be an old USB 1.0 cable, while the Scarlett 2i4 is a USB 2.0 device! After changing the cable to a USB 2.0 one I never had a bluescreen again. And, probably the Scarlett 2i4 also work
