I put down the work of teaching, and I was relaxed for a long time. As before, he threw himself into programming.

Fat Biao had a whim, wanting to make the long-term Pacman game into an arcade machine and sell it for money, but unfortunately the amount of work was a bit huge, which made him feel a little nowhere to start.

It's not as simple as writing a program, arcades in those days were a stand-alone system, and making a game required designing a new machine.

It was a bit difficult to get Fat Biao to come up with a new system from scratch, so he had to come up with the idea of the thousands of machines in his warehouse.

The idea of Feibiao is to make full use of the existing resources, modify those unsalable goods, peel off the original ROM chip that stores game data, and replace it with a game program written by itself.

This avoids the embarrassment of redeveloping hardware and saves time and money.

It's just that this method is theoretically feasible, but it is difficult to implement in practice. The arcade system is strange, there is no standard at all, and the fat standard can't find the data of the substrate at all, so you can only find it out one by one.

Fei Biao is just an electronics enthusiast, and such a difficult subject is really unsolvable, so he has no choice but to ask for help from the long term.

The long answer is simple, no!

"It's easy for me to make a new arcade system, but it's hard to use someone else's system as your own platform when you don't have any information. For example, if you look at the Mac now, it's very simple, but if you are given a bare machine, there are no data tools, how can you still develop, so you must have development tools to do it. Long said.

"It seems that the bamboo basket is still empty. "Fat Biao was a little frustrated, I didn't expect to be able to do it for a long time, it seems that I thought things simple.

"Actually, it's not that difficult. "The mood of the fat standard for a long time is a little low, and he comforts him, "It's nothing more than a few parts, central processing, storage, input and output, scanning, etc., very simple." ”

"What you said is very simple, I just learned it, how can I understand it all at once. ”

"It's useless to learn, I haven't heard of anyone who can succeed by learning. After a long summary, "You must do it, explore step by step, and learn from failures, so that you can grow quickly." In this way, you help me write a program, and I will take you to make an arcade substrate, and I will teach you a package for three months!"

“......”

Haikou for a long time is not boasting, he does have this ability, a computer system is simple to say that it is extremely simple, the key depends on how you look at it, the system is from simple to complex.

Fei Biao is still happy to have someone to guide, he cherishes this rare opportunity, he also has a foundation, otherwise he would not have learned this major, but there is no introduction to computer systems.

Chang Chang writes code with Fat Label during the day, and tinkers with the substrate together in his room at night.

The program is nothing, just step-by-step, and I have been able to do this for a long time, and the progress control is just right, and the icon plug-in of the videoform was quickly completed and sent to Dr. Yu in the United States.

The substrate design took a little time, because it was half taught and half done, and I hadn't touched it for a long time, but everything has changed, it's all computer systems, but it's just a general purpose and a special one.

For the sake of prudence, I specially dismantled an arcade machine for a long time and analyzed the design in it, and after analyzing it, I was sure that it was just about the same as the FC of the year, or even worse.

I used to do piracy for a long time in my dream, which is to crack the original Japanese cartridge, dump the game data and connect it to my own system, and sell it to game dealers. So he's very familiar with the arcade substrate, and he knows what to use to clean the door.

It's just another situation with the fertilizer standard, for a long time, in order to let the fertilizer standard be able to systematically understand the computer design, a set of the simplest computer is specially assembled with the removed components, and there is almost no function except addition calculation.

Simplicity has the benefit of simplicity, at least it can make the fat label clear at a glance. This cell-level host was disassembled and disassembled by the two, and there was almost no time for it to be complete.

However, such manual experiments also made Fei Biao quickly enter the door, no longer obsessed with simple software programming, and finally knew a little bit about what it was and why it was true.

With these foundations, we have long been guided to complicate the system step by step and add more functions. Fat Biao is more interested in this aspect, he reads electronic engineering, and he looks closer to these external devices than anyone else.

Soon, with the deepening of the theoretical knowledge of the fat standard, the functions of this single-board machine are also enriched day by day, and it is officially moving closer to the arcade model.

As a child of a rich family, the vice of Feibiao has gradually emerged, and instead of pursuing the streamlining of procedures, the materials used are becoming more and more luxurious. For example, if the program is large and the memory is insufficient, the first reaction for a long time is to optimize the program, and the idea of fat standard is very simple - add memory!

For this reason, the two have argued more than once, and Fei Biao thinks that the hardware is getting cheaper and cheaper, so what's the matter with adding materials. For a long time, he resolutely spurned this kind of loser behavior, "Writing programs is an art, simplicity is beauty, and now is not the time when memory is everywhere!"

Disputes are disputes, and the relationship between the two is still very good, after all, this is just a difference in philosophy. Later, I got tired of this endless optimization behavior for a long time, and I was lazy.

As a result, the materials used in this generalized arcade substrate are becoming more and more advanced, the cost has skyrocketed, and the storage capacity has reached the limit of an 8-bit processor.

However, the benefits of this are obvious, the stage is bigger, the long-term program has room to maneuver, many ideas are spewed out, and the original insurmountable technical obstacles are solved.

In private, I have been thinking for a long time whether I am outdated, and I am not sensible yet.

However, there is still a problem, that is, the graphics performance of the system still cannot be improved, even if the performance of the processor is still strong.

Fat Biao and Changjiu have also discussed this problem, and they both feel that it is unsolvable, which is the basic reason, unless they switch to a better processor.

The substrate they designed is currently using the cheapest CPU - 6502, one is cheap, the performance is enough to use, and the other is familiar with this for a long time, he doesn't know how many times he has studied this system in his dream, and many of the FC compatible machines of the year are long-term designs. Xiaobawang is endlessly fun, I guess many people have heard of it.

"Why is Uncle Yu's arcade picture so easy to pinch?" Fat Biao scratched his head, puzzled there.

"That's because it has a special graphics chip driver, the picture is processed by the graphics chip, and the CPU is only used as a tool to control the overall situation. Chang replied.

"Then add it. A word woke up the person in the dream, and Fat Biao blurted out as a matter of course.

"Nonsense, I don't know how to add it? The question is where to find this kind of thing?" said angrily for a long time, "and it's so expensive, the cost of your current board is already high enough, and then you use graphics chips, who will buy your things." ”

"I'm not happy, it's a big deal to play by myself. "The fat label is in a hurry, and it feels very uncomfortable that there is something that cannot be played.

"Well, go find it, I don't know of any company that makes this thing. Anyway, I can't do it without information. "It's not a long time, it's really difficult, the complexity of the graphics system can be compared to the whole computer, and the long term is just rough.

"You just see, I don't believe in things that money can't buy?" said Fat Biao confidently.

Dizzy, I thought I had a cold, but it turned out that I had drunk too much.
