About the gadgets and technologies I like to play and hack.

Retro FC Plus 168 in 1 games list

I recently felt nostalgic and wanted to play some of the 8-bit NES games from my childhood. Having an emulator such as OpenEMU that can run NES roms is great but owning a physical device is even better.

Thanks to AliExpress I acquired a portable 8-bit game console with 168 games build in. It’s clone of Game Boy Mini called Coolbaby RS-6 A or Retro FC Plus known by the user manual. It’s a cool little gadget which I will review in details later.

I brought myself a Christmas present

After being upgraded to June 2017 iMac 27″ 5k Retina at work, and using it for a week, I decided it’s about time to purchase myself an iMac. My first impression with this machine is fantastic, everything just works (fast and smooth) and the 5K Retina is amazing.

Today (after being financially stable, after some time ๐Ÿ™‚ ) I ordered 27″ iMac 5K Retina equipped with 4.2GHz Quad-Core Intel Core i7, 16GB 2400MHz DDR4 (will be upgraded to 32 or 64 GB later), 2TB Fusion Drive and Radeon Pro 580 with 8GB VRAM.

It will arrive around 20 Jan 2018. It will be a nice time to start developing apps for iOS and bring VMSoft to the app store as well. Also a lot of my clients were asking me when will I start developing for iOS.

Fighting spammers: Removing Website URL Field from Comment Form

I’m tired of receiving massive amount of spam comments on my blog (1280 spam comments for about a month) and doing:

DELETE FROM `wp_comments` WHERE `comment_approved` = 0

Beside using SI Captcha Anti-Spam which does pretty good job in keeping some of the automated spam bots at bay, I noticed some trend in the spam comments flooding my posts, they are all full of SEO keywords and they are heavy abusing the Website field in the comment form.

Here is a small “plugin” which will remove (unset) the URL field in the comments form:

Plugin Name: Remove Website field from comments.
function custom_comment_fields( $fields ){
  return $fields;
add_filter( 'comment_form_default_fields', 'custom_comment_fields' );

Create a file in /wp-content/plugins/ with the code a bough. Go to the ‘Plugins’ section of the admin panel and activate the newly created plugin named “Remove Website field from comments”.

Yey, no more “Website” field in the “Leave a Reply” section ๐Ÿ™‚

Alternative workplace. It really gives you motivation.

Making small changes in my day to day work as ‘indie’ game dev really helps. Today I decided I should work in the smallest room in the house on my laptop while listening to Al Bano & Romina Power.


I don’t know why, but it really increases my productivity, and I’m moving faster toward releasing the public alpha of my new mobile game.

Connecting my PC XT clone to the network: Part 1 – Ethernet adapter

I currently work on connecting my PC XT clone to my home network. But why? What are the benefits of connecting a 30 years old machine to the network?

It gives me one more reason to fire up my Pravetz 16 ๐Ÿ™‚ It would be cool chatting on IRC on that monochrome (green and black) monitor, running an FTP server for file transfers between the PC XT and other PC’s on the network or an HTTP server, etc…

The PC XT will be connected to the network using the so called ‘Thin Ethernet‘ (10Base2) using a coaxial cable and BNC connectors. Why? Because finding 8-bit ISA compatible Ethernet card is extremely rare nowadays, and chances to find one with RJ45 connector are close to zero.

My long search for 8-bit ISA network adapter finally gave results and for 10$ I’m an owner of PLUS & PLUS PCN-001.

Plus & Plus PNC-001 Ethernet adpater

Plus & Plus PNC-001 Ethernet adpater

It’s 10Mbps Ethernet card with support for coaxial and DIX transceiver wiring. It has an option for a boot ROM but mine don’t have a chip. This card is a clone of AMERICAN RESEARCH CORPORATION PNC-001, it’s NE1000 compatible and supported by the NE1000 driver for DOS available in the along with many other packet drives, thanks to Crynwr Software!

After a bit of googling I found the required information on how to configure the adapter here. That exact same information is copy / pasted at the end of this post for future references.

Setting the IRQ to 2, the I/O base address to 200h, and disabling the boot ROM and DMA settings, changing the cable type jumpers from ‘DIX transceiver via DB-15 port’ to ‘RG-58A/U 50ohm coaxial’ I booted the PC, loaded the NE1000 driver

C:\>ne1000 0x7E 2 0x200

UPDATE 16/02/2016: I was having problems receiving network packets, changing the IRQ to 5 and I/O base address to 0x280h resolved the problem.

NE1000 packet driver loaded

NE1000 packet driver loaded

and success! The card is working! 10$ well spend ๐Ÿ™‚

NOTE: Installation instructions for packet drivers are in INSTALL.DOC (

The Ethernet adapter is now configured and working properly. This concludes Part 1 of the series of articles about connecting my PC XT to the network. Later I will review other vital network component. The Surecom Ether Perfect 517T hub with BNC connector.
