We have a wide range of action game genres, such as shooter, fighting games and a lot more.

Also, you will often find that the action games for PC of multi-platform titles are popular due to added effects – Batman: Arkham City and Tomb Raider are the examples which seem far better on PC. Without any doubt, the early part of the 21st century has witnessed an exponential increase in PC graphical grunt, to produce not only great gameplay, but eye-catching visuals.

You should consider full version Battlefield and Call of Duty, which came out on PC and now have become some of the most profitable multi-platform franchises. Then they eventually came out with the auto adjusting game cards and sound cards that had joystick ports that worked with whatever speed computer they were put in.People started playing out some of the most successful action game franchises on PC. If the card was too old or wasn't set to the correct speed, you would get anything from not being able to calibrate the axis to the joystick/gamepad not working at all.
One of the best was the Gravis card that used an external POT so you had a very wide range of adjustability. Past that and you would need a speed selectable game card. The speed switching game cards were for compatibility with different speed systems.Ī lot of old sound cards would only work on systems up to a certain speed. Still wouldn't solve the case of a disconnected device of course. I suppose the idea here was that the switch change the discharge speed of the capacitors, so you could reduce CPU load, by requiring less absolute time to measure a full axis. That Codeview program looks useful, do you know where I can get it?

Probably isn't if I tried it myself though 🤣. (I suppose the real hackers would be laughing their asses off if they saw that I'm using Microsoft CodeView instead of some leet debugger tool.)

Since this occurs only once in LOTUS.DAT, I knew that this would be the correct position. Finding several instances of F7 F1 there, I took the last byte from the preceding instruction (FB) to search for the three-byte sequence FB F7 F1.

Finding nothing but noticing that LOTUS.EXE is extremely small, I expected that the main program code would be in LOTUS.DAT instead. I then searched for those two bytes in LOTUS.EXE.
You can see that to the left of the offending DIV instruction are the two bytes (F7 F1) that make up its machine code. Ran the game in Microsoft CodeView instead of bailing to DOS upon encountering the divide error, it will pause and highlight the offending machine instruction (see screenshot). And if I did I would probably be looking in the exe, not the dat file, 🤣. How do you even find these fixes? I wouldn't have any idea where to look. Is it the same bug as the well known Borland runtime error 200 that happens with certain other games? Wow, thank you so much, that fixed it! It runs without any slowdown tools now and I no longer need to have any controllers connected! And the framerate is just perfect, I don't recall this game ever running as smooth as it does now!Īnd you're right, I said "invalid opcode error" but that happened with some other game.
Have you tried running the game on a different machine, with a different game controller card or at least with a different joystick cable? It's not out of the question that either the controller card or the cable might give the game false positives by reporting sponanteous bit changes. It worked correctly (as far as I can tell) with that change applied at full machine speed.

I did not use any slowdown utility I first successfully ran it with the CPU's internal cache disabled, then at full speed after figuring out how to patch away the "invalid opcode error" (actually a divide overflow): open LOTUS.DAT with a hex editor, search for FB F7 F1 and replace with FB 90 90. I have just run Lotus III version 14/07/93 on a Pentium II DOS machine with no joysticks attached at all.
